f7854dd90f introspection: Build fixes
This patch merges in substantial work from
Emmanuele Bassi <ebassi@linux.intel.com>

* Use new introspection --include-uninstalled API since we don't want
  to try to find the clutter-1.0.pc file before it's installed.
* Use --pkg-export for Clutter-1.0.gir, since we want the .gir file to
  contain the associated pkg-config file.
* Drop the use of --pkg for dependencies; those come from the associated
  .gir files.  (Actually, --pkg is almost never needed)
* Add --quiet

70dc3ecbd6 egl: Fix the installed headers
• Use the public COGL_HAS_GLES[12] define instead of the HAVE_COGL_*
   ones which are private and defined in config.h,
 • Install clutter-egl-headers.h which is needed by clutter-egl.h,
 • Remove clutter-stage.h as it's uneeded and does not work since the
   single clutter.h include policy,
 • Install the egl headers into their own egl directory as the x11 and
   glx backends do. The include should then be <clutter/egl/clutter-egl.h>,
   so document it. It does not really break anything as nobody could
   have used those broken headers.

e1e5db0032 cex100: Add a Clutter EGL backend for CE3100/CE4100 SoCs
Intel CE3100 and CE4100 SoCs are designed for TVs. They have separate
framebuffers that are blended together by a piece of hardware to make
the final output. The library that allows you to initialize and
configure those planes is called GDL. A EGL GDL winsys can then be
use with those planes as NativeWindowType to select which plane to use.

This patch adds a new ClutterBackendCex100 backend that can be
selected at compile time with the new --with-flavour=cex100 option.

12a5bf2e06 offscreen-effect: Rename create_target to create_buffer
*** This is an API change ***

The create_target() virtual function should return a CoglHandle to a
texture; clutter_offscreen_effect_get_target(), instead, returns a
CoglMaterial to be painted in the implementation of the paint_target()
virtual function.

Instead of equating textures with materials, and confusing the user of
the API, we should mark the difference more prominently.

First of all, we should return a CoglMaterial* (now that we have that
as a public type) in get_target(); having handles all over the place
does not make it easier to distinguish the semantics of the virtual
functions.

Then we should rename create_target() to create_texture(), to make it
clear that what should be returned is a texture that is used as the
backing for the offscreen framebuffer.

2e12768e3c win32: Fix the check for the 'IN_DESTRUCTION' flag
Commit eae4561929 tried to clean how it checks for the private actor
flags. However the check for the 'IN_DESTRUCTION' flag in the Win32

context. This was causing _cogl_check_driver_valid to fail later and
then the realize would get stuck in a infinite loop.

965907deb3 Cache a full pick render if we have a static stage
The idea is that if we see multiple picks per frame then that implies
the visible scene has become static. In this case we can promote the
next pick render to be unclipped so we have valid pick values for the
entire stage. Now we can continue to read from this cached buffer until
the stage contents do visibly change.

Thanks to Luca Bruno on #clutter for this idea!

also fix a problem with clutter-shader too in that previously we weren't

db0c15aee8 cogl-atlas: Verify that the chosen initial size is supported
CoglAtlas chooses a fairly large default initial size of either
512x512 or 1024x1024 depending on the texture format. There is a
chance that this size will not be supported on some platforms which
would be catastrophic for the glyph cache because it would mean that
it would always fail to put any glyphs in the cache so text wouldn't
work. To fix this the atlas code now checks whether the chosen initial
size is supported by the texture driver and if not it will get halved
until it is supported.

b9f9ea3a9c cogl-atlas: Use _cogl_texture_driver_size_supported
Previously when creating a new rectangle map it would try increasingly
larger texture sizes until GL_MAX_TEXTURE_SIZE is reached. This is bad
because it queries state which should really be owned by the texture
driver. Also GL_MAX_TEXTURE_SIZE is often a conservative estimate so
larger texture sizes can be used if the proxy texture is queried
instead.

72029e14db cogl-rectangle-map: Record largest gap rather than the remaining space
Previously each node in the rectangle map tree would store the total
remaining space in all of its children to use as an optimization when
adding nodes. With this it could skip an entire branch of the tree if
it knew there could never be enough space for the new node in the
branch. This modifies that slightly to instead store the largest
single gap. This allows it to skip a branch earlier because often
there would be a lot of small gaps which would add up to enough a
space for the new rectangle, but the space can't be used unless it is
in a single node.

The rectangle map still needs to keep track of the total remaining
space for the whole map for the debugging output so this has been
added back in to the CoglRectangleMap struct. There is a separate
debugging function to verify this value.

2b5bb06bed cogl-atlas: Try the next size when there would be less than 6% waste
Previously when the atlas needs to be migrated it would start by
trying with the same size as the existing atlas if there is enough
space for the new texture. However even if the atlas is completely
sorted there will always be some amount of waste so when the atlas
needs to grow it would usually end up redundantly trying the same size
when it is very unlikely to fit. This patch changes it so that there
must be at least 6% waste available after the new texture is added
otherwise it will start with the next atlas size.

e080e824ee cogl-rectangle-map: Use a GArray for the stack
When iterating over the rectangle map a stack is used to implement a
recursive algorithm. Previously this was slice allocating a linked

avoid frequent allocations which is a little bit faster.

0e2d18d700 cogl-rectangle-map: Store the remaining space per node
Previously the remaining space was managed as part of the
CoglRectangleMap struct. Now it is stored per node so that at any
point in the hierarchy we can quickly determine how much space is
remaining in all of the node's children. That way when adding a
rectangle we can miss out entire branches more quickly if we know that
there is no way the new rectangle would fit in that branch.

This also adds a function to recursively verify the cached state in
the nodes such as the remaining space and the number of
rectangles. This function is only called when the dump-atlas-image
debug flag is set because it is potentially quite slow.

e609a658a4 cogl-atlas: Increase the default minimum texture size

d03fbf9f64 cogl-pango: Use a CoglAtlas to maintain the glyph cache
The glyph cache is now stored in a CoglAtlas structure instead of the
custom atlasing code. This has the advantage that it can share code
with the main texture atlas and that it supports reorganizing the
atlas when it becomes full. Unlike the texture atlas, the glyph cache
can use multiple atlases which would be neccessary if the maximum
texture size is reached and we need to create a second
texture. Whenever a display list is created it now has to register a
callback with the glyph cache so that the display list can be
recreated whenever any of the atlases are reorganized. This is needed
because the display list directly stores texture coordinates within
the atlas texture and they would become invalid when the texture is
moved.

The ensure_glyphs_for_layout now works in two steps. First it reserves
space in the atlas for all of the glyphs. The atlas is created with
the DISABLE_MIGRATION flag so that it won't actually copy any textures
if any rearranging is needed. Whenever the position is updated for a
glyph then it is marked as dirty. After space for all of the glyphs
has been reserved it will iterate over all dirty glyphs and redraw
them using Cairo. The rendered glyph is then stored in the texture
with a sub texture update.

The glyphs need to all be set at the right location before starting to
create the display list because the display list stores the texture
coordinates of the glyph. If any of the glyphs were moved around then
the parts of the display list that was created already would become
invalid. To make this work, ensure_glyphs_for_layout is now always
called before rendering a layout or a layout line.

047227fbd7 cogl-atlas: Support multiple formats and clearing the texture
_cogl_atlas_new now has two extra parameters to specify the format of
the textures it creates as well as a set of flags to modify the
behavious of the atlas. One of the flags causes the new textures to be
cleared and the other causes migration to avoid actually copying the
textures. This is needed to use CoglAtlas from the pango glyph cache
because it needs to use COGL_PIXEL_A_8 and to clear the textures as it
does not fill in the gaps between glyphs. It needs to avoid copying
the textures so that it can work on GL implementations without FBO
support.

89c535f50d cogl-material: Compare whether textures are equal by their GL handle

batched together. Instead it now tries to determine the underlying GL
handle using either the slice override or _cogl_texture_get_gl_texture
and then compares those.

8538bdbdea cogl-atlas-texture: Accept formats with different component orders
When filtering on allowed formats for atlas textures, it now masks out
the BGR and AFIRST bits in addition to the premult bit. That way it
will accept RGB and RGBA formats in any component order.

In theory it could also accept luminance and alpha-only textures but I
haven't added this because presumably if the application has requested
these formats then it has some reason not to use a full RGB or RGBA
texture and we should respect that.

d14e294d86 Add ClutterTableLayout, a layout showing children in rows and columns
A TableLayout is a layout manager that allocates its children in rows
and columns. Each child is assigned to a cell (or more if a cell span
is set).

The supported child properties are:

  • x-expand and y-expand: if this cell with try to allocate the
    available extra space for the table.
  • x-fill and y-fill: if the child will get all the space available in
    the cell.
  • x-align and y-align: if the child does not fill the cell, then
    where the child will be aligned inside the cell.
  • row-span and col-span: number of cells the child will allocate for
    itself.

Also, the TableLayout has row-spacing and col-spacing for specifying
the space in pixels between rows and between columns.

We also include a simple test of the layout manager, and the
documentation updates.

The TableLayout was implemented starting from MxTable and
ClutterBoxLayout.

07b01888ba actor: Add allocate_align_fill()
Layout managers are using the same code to allocate a child while taking
into consideration:

  • horizontal and vertical alignment
  • horizontal and vertical fill
  • the preferred minimum and natural size, depending
    on the :request-mode property
  • the text direction for the horizontal alignment
  • an offset given by the fixed position properties

Given the amount of code involved, and the amount of details that can go
horribly wrong while copy and pasting such code in various classes - let
alone various projects - Clutter should provide an allocate() variant
that does the right thing in the right way. This way, we have a single
point of failure.

8d51617979 Conditionally use g_object_notify_by_pspec
This adds a wrapper macro to clutter-private that will use
g_object_notify_by_pspec if it's compiled against a version of GLib
that is sufficiently new. Otherwise it will notify by the property
name as before by extracting the name from the pspec. The objects can
then store a static array of GParamSpecs and notify using those as
suggested in the documentation for g_object_notify_by_pspec.

Note that the name of the variable used for storing the array of
GParamSpecs is obj_props instead of properties as used in the
documentation because some places in Clutter uses 'properties' as the
name of a local variable.

Mose of the classes in Clutter have been converted using the script in
the bug report. Some classes have not been modified even though the
script picked them up as described here:

json-generator:

 We probably don't want to modify the internal copy of JSON

behaviour-depth:
rectangle:
score:
stage-manager:

 These aren't using the separate GParamSpec* variable style.

blur-effect:
win32/device-manager:

 Don't actually define any properties even though it has the enum.

box-layout:
flow-layout:

  Have some per-child properties that don't work automatically with
  the script.

clutter-model:

  The script gets confused with ClutterModelIter

stage:

  Script gets confused because PROP_USER_RESIZE doesn't match
  "user-resizable"

test-layout:

  Don't really want to modify the tests

The special handling for texture unit 1 caught the case where unit
1 was changed for transient purposes, but didn't properly handle
the case where the actual non-transient texture was different between
two materials with no transient binding in between.

If the actual texture has changed when flushing, mark unit 1 as dirty
and needing a rebind.

This makes CoglProgram/Shader automatically detect when the user has
given an ARBfp program by checking for "!!ARBfp1.0" at the beginning of
the user's source.

ARBfp local parameters can be set with cogl_program_uniform_float
assuming you pass a @size of 4 (all ARBfp program.local parameters
are vectors of 4 floats).

This doesn't expose ARBfp environment parameters or double precision

instead makes the API public because until we implement our planned

Cogl.

The plan is to also support ARBfp with the cogl_program/shader API so
this API will also allow clutter-gst to stop using direct OpenGL calls
that conflict with Cogl's state tracking.

1314d0b1a7 material: chain up in layer_pre_change_notify
A change to a layer is also going to be a change to its owning material
so we have to chain up in _cogl_material_layer_pre_change_notify and
call _cogl_material_pre_change_notify. Previously we were only
considering if the owning material was referenced in the journal but

eeac7c5f43 material: fix initialization of sparse properties
In _cogl_material_pre_change_notify we need to identify if it's a sparse
property being changed and if so initialize the state group if the given
material isn't currently the authority for it.

Previously we were unconditionally calling
_cogl_material_initialize_state which would e.g. NULL the layer
differences list of a material each time a layer change was notified.

It would also call _cogl_material_initialize_state for non-sparse
properties which should always be valid at this point so the function
has been renamed to _cogl_material_initialize_sparse_state to make this
clearer with a corresponding g_return_if_fail check.

d489832688 material: fix copying of material layer differences
This fixes how we copy layer differences in
_cogl_material_copy_layer_differences.

We were making a redundant g_list_copy of the src differences and then
iterating the src list calling _cogl_material_add_layer_difference for
each entry which would double the list length, but the initial copy
directly referenced the original layers which wasn't correct.

Also we were initializing dest->n_layers before copying the layer
differences but the act of copying the differences will re-initialize
n_layers to 0 when adding the first layer_difference since it will
trigger a layer_pre_change_notify and since the dest material isn't yet
a STATE_LAYERS authority the state group is initialized before allowing
the change.

fcbfd4ec34 cogl-material: Unref the texture when reverting authority
When the texture is set on a layer so that it is back to the parent's
texture it would clear the texture change flag but it wouldn't unref
the texture. The free function for a material layer does not unref the
texture if the change flag is cleared so the texture would end up
leaking. This happens for ClutterTexture because it disposes the
texture by setting layer 0 of the material to COGL_INVALID_HANDLE
which ends up the same as the default material.

069266f3ed layout-manager: Freeze ::layout-changed when creating LayoutMeta
LayoutMeta instances are created lazily. If an actor is added to a
container with a layout manager then the first time the layout manager
might be creating the LayoutMeta instance could be during the allocation
cycle caused by calling clutter_actor_show(). When a LayoutMeta is
instantiated for the first time, a list of properties can be set - and
this might lead to the emission of the ::layout-changed signal. The
signal is, most typically, going to cause a relayout to be queued, and a
warning will be printed on the terminal.

We should freeze the emission of the ::layout-changed signal during the
creation of the LayoutMeta instances, and thaw it after that.

609560b1cb glx: Unconditionally select X11/GLX events
Currently, we select input events and GLX events conditionally,
depending on whether the user has disabled event retrieval.

We should, instead, unconditionally select input events even with event
retrieval disabled because we need to guarantee that the Clutter
internal state is maintained when calling clutter_x11_handle_event()
without requiring applications or embedding toolkits to select events
themselves. If we did that, we'd have to document the events to be
selected, and also update applications and embedding toolkits each time
we added a new mask, or a new class of events - something that's clearly
not possible.

See:

  http://bugzilla.clutter-project.org/show_bug.cgi?id=998

for the rationale of why we did conditional selection. It is now clear
that a compositor should clear out the input region, since it cannot
assume a perfectly clean slate coming from us.

See:

  http://bugzilla.clutter-project.org/show_bug.cgi?id=2228

for an example of things that break if we do conditional event
selection on GLX events. In that specific case, the X11 server ≤ 1.8
always pushed GLX events on the queue, even without selecting them; this
has been fixed in the X11 server ≥ 1.9, which means that applications
like Mutter or toolkit integration libraries like Clutter-GTK would stop
working on recent Intel drivers providing the GLX_INTEL_swap_event
extension.

This change has been tested with Mutter and Clutter-GTK.

c23b283968 animatable: Allow passing a NULL animation
The Animatable interface was created specifically for the Animation
class. It turns out that it might be fairly useful to others - such as
ClutterAnimator and ClutterState.

The newly-added API in this cycle for querying and accessing custom
properties should not require that we pass a ClutterAnimation to the
implementations: the Animatable itself should be enough.

This is necessary to allow language bindings to wrap
clutter_actor_animate() correctly and do type validation and
demarshalling between native values and GValues; an Animation instance
is not available until the animate() call returns, and validation must
be performed before that happens.

There is nothing we can do about the animate_property() virtual
function - but in that case we might want to be able to access the
animation from an Animatable implementation to get the Interval for
the property, just like ClutterActor does in order to animate
ClutterActorMeta objects.

488e376b7e cogl-bitmap-pixbuf: Avoid copying the buffer in more circumstances
When loading an RGB image GdkPixbuf will pad the rowstride so that the
beginning of each row is aligned to 4 bytes. This was causing us to
fallback to the code that copies the buffer. It is probably safe to
avoid copying the buffer if we can detect that the rowstride is simply
an alignment of the packed rowstride.

This also changes the copying fallback code so that it uses the

b9295bf0e5 cogl-bitmap-pixbuf: Fix the rowstride used when copying a GdkPixbuf
In commit b780413e5a the GdkPixbuf loading code was changed so that
if it needs to copy the pixbuf then it would tightly pack it. However
it was still using the rowstride from the pixbuf so the image would
end up skewed. This fixes it to use the real rowstride.

bb1b1b151e cogl-material: Don't map the shininess value to [0,1]
In OpenGL the 'shininess' lighting parameter is floating point value
limited to the range 0.0→128.0. This number is used to affect the size
of the specular highlight. Cogl materials used to only accept a number
between 0.0 and 1.0 which then gets multiplied by 128.0 before sending
to GL. I think the assumption was that this is just a weird GL quirk
so we don't expose it. However the value is used as an exponent to
raise the attenuation to a power so there is no conceptual limit to
the value.

This removes the mapping and changes some of the documentation.

d76d82c88f cogl-material: Always reset the GLSL program to zero when flushing
When flushing a fixed-function or arbfp material it would always call
disable_glsl to try to get rid of the previous GLSL shader. This is
needed even if current_use_program_type is not GLSL because if an
application calls cogl_program_uniform then Cogl will have to bind the
program to set the uniform. If this happens then it won't update
current_use_program_type presumably because the enabled state of arbfp
is still valid.

The problem was that disable_glsl would only select program zero when
the current_use_program_type is set to GLSL which wouldn't be the case
if cogl_program_uniform was called. This patch changes it to just
directly call _cogl_gl_use_program_wrapper(0) instead of having a
separate disable_glsl function. The current program is cached in the
cogl context anyway so it shouldn't cause any extra unnecessary GL
calls.

6ea2fbc729 Add an internal _cogl_bitmap_new_from_buffer
This function creates a CoglBitmap which internally references a
CoglBuffer. The map and unmap functions will divert to mapping the
buffer. There are also now bind and unbind functions which should be
used instead of map and unmap whenever the data doesn't need to be
read from the CPU but will instead be passed to GL for packing or
unpacking. For bitmaps created from buffers this just binds the
bitmap.

cogl_texture_new_from_buffer now just uses this function to wrap the
buffer in a bitmap rather than trying to bind the buffer
immediately. This means that the buffer will be bound only at the
point right before the texture data is uploaded.

This approach means that using a pixel array will take the fastest
upload route if possible, but can still fallback to copying the data
by mapping the buffer if some conversion is needed. Previously it
would just crash in this case because the texture functions were all
passed a NULL pointer.

b780413e5a Try to avoid copying the GdkPixbuf when it is tightly packed
The docs for GdkPixbuf say that the last row of the image won't
necessarily be allocated to the size of the full rowstride. The rest
of Cogl and possibly GL assumes that we can copy the bitmap with
memcpy(height*rowstride) so we previously would copy the pixbuf data
to ensure this. However if the rowstride is the same as bpp*width then
there is no way for the last row to be under-allocated so in this case
we can just directly upload from the gdk pixbuf. Now that CoglBitmap
can be created with a destroy function we can make it keep a reference
to the pixbuf and unref it during its destroy callback. GdkPixbuf
seems to always pack the image with no padding between rows even if it
is RGB so this should end up always avoiding the memcpy.

The fallback code for when we do have to copy the pixbuf is now
simplified so that it copies all of the rows in a single loop. We only
copy the useful region of each row so this should be safe. The
rowstride of the CoglBitmap is now always allocated to bpp*width
regardless of the rowstride of the pixbuf.

fc12c42a83 cogl-bitmap: Encapsulate the CoglBitmap even internally
The CoglBitmap struct is now only defined within cogl-bitmap.c so that
all of its members can now only be accessed with accessor
functions. To get to the data pointer for the bitmap image you must
first call _cogl_bitmap_map and later call _cogl_bitmap_unmap. The map
function takes the same arguments as cogl_pixel_array_map so that
eventually we can make a bitmap optionally internally divert to a
pixel array.

There is a _cogl_bitmap_new_from_data function which constructs a new
bitmap object and takes ownership of the data pointer. The function
gets passed a destroy callback which gets called when the bitmap is
freed. This is similar to how gdk_pixbuf_new_from_data
works. Alternatively NULL can be passed for the destroy function which
means that the caller will manage the life of the pointer (but must
guarantee that it stays alive at least until the bitmap is
freed). This mechanism is used instead of the old approach of creating
a CoglBitmap struct on the stack and manually filling in the
members. It could also later be used to create a CoglBitmap that owns
a GdkPixbuf ref so that we don't necessarily have to copy the
GdkPixbuf data when converting to a bitmap.

There is also _cogl_bitmap_new_shared. This creates a bitmap using a
reference to another CoglBitmap for the data. This is a bit of a hack
but it is needed by the atlas texture backend which wants to divert
the set_region virtual to another texture but it needs to override the
format of the bitmap to ignore the premult flag.

doesn't make any sense to retain this information because it doesn't
necessarily indicate the format of the actual texture. This patch
changes it to store the internal format instead.

These apps are redrawing the whole screen, so we can avoid clearing the

blending with the stage color being performed.

We can add an private set of hints to ClutterStage, and expose accessors

192cfa7a58 Rename the third texure coordinate from 'r' to 'p'
Using 'r' to name the third component is problematic because that is
commonly used to represent the red component of a vector representing
a color. Under GLSL this is awkward because the texture swizzling for
a vector uses a single letter for each component and the names for
colors, textures and positions are synonymous. GLSL works around this
by naming the components of the texture s, t, p and q. Cogl already
effectively already exposes this naming because it exposes GLSL so it
makes sense to use that naming consistently. Another alternative could
be u, v and w. This is what Blender and Direct3D use. However the w
component conflicts with the w component of a position vertex.

dfea57b45a Add a Cogl texture 3D backend
This adds a publicly exposed experimental API for a 3D texture
backend. There is a feature flag which can be checked for whether 3D
textures are supported. Although we require OpenGL 1.2 which has 3D
textures in core, GLES only provides them through an extension so the
feature can be used to detect that.

The textures can be created with one of two new API functions :-

cogl_texture_3d_new_with_size

 and

cogl_texture_3d_new_from_data

There is also internally a new_from_bitmap function. new_from_data is
implemented in terms of this function.

The two constructors are effectively the only way to upload data to a
3D texture. It does not work to call glTexImage2D with the
GL_TEXTURE_3D target so the virtual for cogl_texture_set_region does
nothing. It would be possible to make cogl_texture_get_data do
something sensible like returning all of the images as a single long
image but this is not currently implemented and instead the virtual
just always fails. We may want to add API specific to the 3D texture
backend to get and set a sub region of the texture.

All of those three functions can throw a GError. This will happen if
the GPU does not support 3D textures or it does not support NPOTs and
an NPOT size is requested. It will also fail if the FBO extension is
not supported and the COGL_TEXTURE_NO_AUTO_MIPMAP flag is not
given. This could be avoided by copying the code for the
GL_GENERATE_MIPMAP TexParameter fallback, but in the interests of
keeping the code simple this is not yet done.

This adds a couple of functions to cogl-texture-driver for uploading
3D data and querying the 3D proxy
texture. prep_gl_for_pixels_upload_full now also takes sets the
GL_UNPACK_IMAGE_HEIGHT parameter so that 3D textures can have padding
between the images. Whenever 3D texture is uploading, both the height
of the images and the height of all of the data is specified (either
explicitly or implicilty from the CoglBitmap) so that the image height
can be deduced by dividing by the depth.

There are many places in the texture backend that need to do
conversion using the CoglBitmap code. Currently none of these
functions can throw an error but they do return a value to indicate
failure. In future it would make sense if new texture functions could
throw an error and in that case they would want to use a CoglBitmap
error if the failure was due to the conversion. This moves the

b7f99ddd3c script: Let ClutterActor parse behaviours
Up until now, the "behaviours" member of an actor definition was parsed
by the ClutterScript parser itself - even though it's not strictly
necessary.

In an effort to minimize the ad hoc code in the Script parser, we should
let ClutterActor handle all the special cases that involve
actor-specific members.

a65429363e Use GL_MAX_TEXTURE_SIZE on GLES when checking supported tex size
Under big GL, _cogl_texture_driver_size_supported uses the proxy
texture to check whether the given texture size is supported. Proxy
textures aren't available under GLES so previously this would just
return TRUE to assume all texture sizes are supported. This patch
makes it use glGetIntegerv with GL_MAX_TEXTURE_SIZE to give a second
best guess.

This fixes the sliced texture backend so that it will use slices when
the texture is too big.

9e1bb31922 Use GL_NEAREST filter in the draw-and-read get_data texture fallback
The fallback for when glGetTexImage is not available renders the
texture to the framebuffer to read the data using glReadPixels. This
patch just sets the COGL_MATERIAL_FILTER_NEAREST filter mode on the
material before rendering to avoid linear filtering which would alter
the texture data.

25cf5979e6 Use cogl_read_pixels in the cogl texture draw-and-read fallback
The fallback for when glGetTexImage is not available draws parts of
the texture to the framebuffer and uses glReadPixels to extract the
data. However it was using cogl_rectangle to draw and then immediately
using raw glReadPixels to fetch the data. This won't cause a journal
flush so the rectangle won't necessarily have hit the framebuffer
yet. Instead it now uses cogl_read_pixels which does flush the
journal.

e454b9cadf cogl-material: Fix some problems with flushing texture overrides
There were a few problems flushing texture overrides so that sliced
textures would not work:

* In _cogl_material_set_layer_texture it ignored the 'overriden'
  parameter and always set texture_overridden to FALSE.

* cogl_texture_get_gl_texture wasn't being called correctly in
  override_layer_texture_cb. It returns a gboolean to indicate the
  error status but this boolean was being assigned to gl_target.

* _cogl_material_layer_texture_equal did not take into account the
  override.

* _cogl_material_layer_get_texture_info did not return the overridden
  texture so it would always use the first texture slice.

8beb49164f cogl-texture: Share the common code in the set_region virtual
There was a lot of common code that was copied to all of the backends
to convert the data to a suitable format and wrap it into a CoglBitmap
so that it can be passed to _cogl_texture_driver_upload_subregion_to_gl.
This patch moves the common code to cogl-texture.c so that the virtual
just takes a CoglBitmap that is already in the right format.

0577c81c3b cogl-texture: Share the common code in the get_data virtual
Previously cogl_texture_get_data would pretty much directly pass on to
the get_data texture virtual function. This ended up with a lot of
common code that was copied to all of the backends. For example, the
method is expected to return the required data size if the data
pointer is NULL and to calculate its own rowstride if the rowstride is
0. Also it needs to convert the downloaded data if GL can't support
that format directly.

This patch moves the common code to cogl-texture.c so the virtual is
always called with a format that can be downloaded directly by GL and
with a valid rowstride. If the download fails then the virtual can
return FALSE in which case cogl-texture will use the draw and read
fallback.

ab05f6bfb1 cogl-material: Add support for point sprites
This adds a new API call to enable point sprite coordinate generation
for a material layer:

void
cogl_material_set_layer_point_sprite_coords_enabled (CoglHandle material,
                                                     int layer_index,
                                                     gboolean enable);

There is also a corresponding get function.

Enabling point sprite coords simply sets the GL_COORD_REPLACE of the
GL_POINT_SPRITE glTexEnv when flusing the material. There is no
separate application control for glEnable(GL_POINT_SPRITE). Instead it
is left permanently enabled under the assumption that it has no affect
unless GL_COORD_REPLACE is enabled for a texture unit.

137790bec9 cally: Refactoring "window:create" and "window:destroy" emission code
Previously "window:create" and "window:destroy" were emitted on
CallyUtil. Although it works, and CallyUtil already have callbacks to
stage_added/removed signals, I think that it is more tidy/clear to do
that on CallyRoot:

  * CallyRoot already has code to manage ClutterStage addition/removal

  * In fact, we can see CallyRoot as the object exposing the a11y
    information from ClutterStageManager, so it fits better here.

  * CallyUtil callbacks these signals are related to key event
    listeners (key snooper simulation). One of the main CallyUtil
    responsabilities is managing event (connecting, emitting), so I
    would prefer to not start to add/mix more functionalities here.

Ideally it would be better to emit all CallyStage methods from
CallyStage, but it is clear that "create" and "destroy" are more easy
to emit from a external object

Previously cogl_set_fog would cause a flush of the Cogl journal and
would directly bang the GL state machine to setup fogging. As part of
the ongoing effort to track most state in CoglMaterial to support
renderlists this now adds an indirection so that cogl_set_fog now just
updates ctx->legacy_fog_state. The fogging state then gets enabled as a
legacy override similar to how the old depth testing API is handled.

3570852b02 cogl: expose the semantic differences of gl/gles2 npot textures
This adds three new feature flags COGL_FEATURE_TEXTURE_NPOT_BASIC,
COGL_FEATURE_TEXTURE_NPOT_MIPMAP and COGL_FEATURE_TEXTURE_NPOT_REPEAT
that can tell you if your hardware supports non power of two textures,
npot textures + mipmaps and npot textures + wrap modes other than
CLAMP_TO_EDGE.

The pre-existing COGL_FEATURE_TEXTURE_NPOT feature implies all of the
above.

By default GLES 2 core supports npot textures but mipmaps and repeat
modes can only be used with power of two textures. This patch also makes
GLES check for the GL_OES_texture_npot extension to determine if mipmaps
and repeating are supported with npot textures.

8a5aed36fe pixel-array: Only allow allocation of arrays with a 2D size
This removes cogl_pixel_array_new which just took a size in bytes.

Without the image size and pixel format then the driver often doesn't
have enough information to allocate optimal GPU memory that can be
textured from directly. This is because GPUs often have ways to
spatially alter the layout of a texture to improve cache access patterns
which may require special alignment and padding dependant in the images
width, height and bpp.

Although currently we are limited by OpenGL because it doesn't let us
pass on the width and height when allocating a PBO, the hope is that we
can define a better extension at some point.

header is only included internally when building the tesselator/ files
so it shouldn't affect the rest of Cogl.

GLES also doesn't have a GLdouble type so we just #define this to be a
regular double.

b74c722670 cogl-material: Don't doubly ref the parent in cogl_material_copy
cogl_material_copy was taking a reference on the original texture when
making a copy. However it then calls _cogl_material_set_parent on the
material which also takes a reference on the parent. The second
reference is cleaned up whenever _cogl_material_unparent is called and
this is also called by _cogl_material_free. However, it seems that
nothing was cleaning up the first reference. I think the reference is
entirely unnecessary so this patch removes it.

daf19205e0 align-constraint: Follow the position of the source
The AlignConstraint update is using only the width/height of the source,
but it should also take into account the position.

Also, instead of using the ::notify signal, it should follow the
BindConstraint, and switch to the ::allocation-changed signal, since
it's less expensive (one emission instead of four notifications, one for
each property we use).

b625d94362 cogl: don't include cogl-vector.h twice in cogl.h
cogl-vector.h should only be included by cogl.h when
COGL_ENABLE_EXPERIMENTAL_API is defined. This removes the unguarded
duplicate include.

534472a0d4 cogl: declare experimental symbols consistently
We had several different ways of exposing experimental API, in one case
the symbols had no special suffix, in two other ways the symbols were
given an _EXP suffix but in different ways.

This makes all experimental API have an _EXP suffix which is handled
using #defines in the header so the prototypes in the .c and .h files
don't have the suffix.

The documented reason for the suffix is so that anyone watching Cogl for
ABI changes who sees symbols disappear will hopefully understand what's
going on.
