ed39948ccf colorize-effect: Do not inherit from ShaderEffect
See commits:

  7daeb217 blur-effect: Do not inherit from ShaderEffect
  1ec57743 desaturate-effect: Do not inherit from ShaderEffect

We might avoid using shaders at all in the future for simple effects.

d10ebe9fca effects: Check before using the cogl_shader_* API
Since BlurEffect and DesaturateEffect are using the shader API
implicitly and not using ClutterShaderEffect, we need to check if the
underlying GL implementation supports the GLSL shading language and warn
if not.

1ec577438e desaturate-effect: Do not inherit from ShaderEffect
Hide the fact that we're using a fragment shader, in case we're able in

7daeb217bd blur-effect: Do not inherit from ShaderEffect
We might want to switch the BlurEffect from a box-blur to a
super-sampling of the texture target, in order to make it cheap(er).
If we inherit from ShaderEffect, though, we're setting in stone the
fact that we are going to use a fragment shader for blurring.

Since there is not parametrization of the blur, the code necessary
to implement effect is pretty small, and we can use the Cogl API
directly.

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.

02b7bf3635 test-flow-layout: Use BindConstraints

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

de8276105f Always bind a new texture to unit 1 when necessary
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.

09e664c349 cogl: Allow setting ARBfp source on a CoglShader
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
local parameters.

f781bcec7e material: Add cogl_material_{get,set}_user_program
Previously we had an internal only _cogl_material_set_user_program to
redirect legacy usage of cogl_program_use() through CoglMaterial. This
instead makes the API public because until we implement our planned
"snippet" framework we need a stop-gap solution for using shaders in
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
that ignores that it might also have dependants. We no longer need to
flush the journal directly in layer_pre_change_notify.

8556617546 material: unlink old layer from owner when replacing
In _cogl_material_layer_pre_change_notify when we see that a layer has
dependants and it can't be modified directly then we allocate a new
layer. In this case we also have to link the new layer to its required
owner. If the immutable layer we copied had the same owner though we
weren't unlinking that old layer.

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.

0e2880b067 material: don't dereference layer->texture directly
In _cogl_material_texture_storage_change_notify we were potentially
dereferencing layer->texture without checking first that it is the
authority of texture state. We now use
_cogl_material_layer_get_texture() instead.

1943b8e544 glx: Depend on libdrm
DRM is available on more platforms than Linux (e.g. kFreeBSD), but
Clutter currently FTBFS there because of not being an alternative to
the __linux__ code (where it should be HAVE_DRM).

Instead of copying the DRM data structures, we should use libdrm when
falling back to directly requesting to wait for the vblank.
