8afb091f56 animator: retain ease-in/interpolation when changing first key
Duplicate the existing ease-in/interpolation mode for the property when
removing, replacing the first key for a property or adding a new first

d45395d78b animator: fix crash when setting keys on running animator
When inserting or modifying keys of a running animator the internal
iterators per property could go out of sync. Reinitializing the
iterators if the timeline is running avoids this.

9ebd5fd935 Implement accessors for the color bits in a framebuffer
Instead of using cogl_get_bitmasks() to query the GL machinery for the
size of the color bits, we should store the values inside the
CoglFramebuffer object and query them the first time we set the framebuffer
as the current one.

Currently, cogl_get_bitmasks() is re-implemented in terms of
cogl_framebuffer_get_*_bits(). As soon as we are able to expose the
CoglOnscreen framebuffer object in the public API we'll be able to
deprecate cogl_get_bitmasks() altogether.

d8e1bd989c Ignore unexpected GLX_BufferSwapComplete
A server that supports GLX_BufferSwapComplete will always send
these events, so we should just silently ignore them if we've
chosen not to take advantage of the INTEL_swap_event GLX
extension.

e477768bd8 cogl-texture-2d-sliced: Use the converted bitmap when uploading
When uploading texture data the cogl-texture-2d-sliced backend was
using _cogl_texture_prepare_for_upload to create a bitmap suitable for
upload but then it was using the original bitmap instead of the new
bitmap for the data. This was causing any format conversions performed
by cogl_texture_prepare_for_upload to be ignored.

405d529f44 cogl-texture: Don't attempt to use GL to convert formats under GLES
In commit abe91784c4 I changed cogl-texture so that it would use the
OpenGL mechanism to specify a different internal texture format from
the image format so that it can do the conversion instead of
Cogl. However under GLES the internal format and the image format must
always be the same and it only supports a limited set of formats. This
patch changes _cogl_texture_prepare_for_upload so that it does the
conversion using the cogl bitmap code when compiling for GLES.

8530b7946a cogl-material: Fix the check to prevent using too many layers
There was a check at the bottom of the loop which sets up the state
for each of the layers so that it would break from the loop when the
maximum number of layers is reached. However after doing this it would
not increment 'i'. 'i' is later used to disable the remaining layers
so it would end up disabling the last layer it just set up.

This patch moves the check to be part of the loop condition so that
the check is performed after incrementing 'i'.

a3bc4a6009 test-cogl-materials: Add a test using the maximum number of layers
This adds a test which creates a material using the maximum number of
layers. All of the layers are assigned a white texture except the last
which is set to red. The default combine mode is used for all of the
layers so the final fragment should end up red.

Currently Cogl doesn't provide a way to query the maximum number of
layers so it just uses glGetIntegerv instead. This might cause
problems on GLES 2 because that adds additional restrictions on the
number of layers.

It also tests intersections by drawing a self-intersecting path and a
path with two sub-paths that overlap. Where the path overlaps it
should be inverted.

abc64a2c67 cogl-clip-stack: Use orientation of the polygon to set clip planes
Previously the clip stack code was trying to detect when the
orientation of the on-screen rectangle had changed by checking if the
order of the y-coordinates on the left edge was different from the
order the x-coordinates on the top edge. This doesn't work for some
rotations which was causing the clip planes to clip the wrong side of
the line. This patch makes it detect the orientation by calculating
the signed area which is a standard computer graphics algorithm.

44c86fcead cogl-path: Don't try to union sub paths
When drawing a path with only a single sub path, Cogl uses the
'even-odd' fill rule which means that if a part of the path intersects
with another part then the intersection would be inverted. However
when combining sub paths it treats them as separate paths and then
unions them together. This doesn't match the semantics of the even-odd
rule in SVG and Cairo. This patch makes it so that a new sub path is
just drawn as another triangle fan so that it will continue to invert
the stencil buffer. This is also much simpler and more efficient as
well as being more correct.

78dc59b348 picking: Read the colour value using COGL_PIXEL_FORMAT_RGBA_8888_PRE
In commit c0a553163b I changed the format used to read the picking
pixel to COGL_PIXEL_FORMAT_RGB_888 because it was convenient to avoid
the premult conversion. However this broke picking on GLES on some
platforms because for that glReadPixels is only guaranteed to support
GL_RGBA with GL_UNSIGNED_BYTE. Since the last commit cogl_read_pixels
will always use that format but it will end up with a conversion back
to RGB_888. This patch avoids that conversion and avoids the premult
conversion by reading in RGBA_8888_PRE.

0cb09cd40d cogl_read_pixels: Always use GL_RGBA/GL_UNSIGNED_BYTE under GLES
Under GLES glReadPixels is documented to only support GL_RGBA with
GL_UNSIGNED_BYTE and an implementation specfic format which can be
fetched with glGet, GL_IMPLEMENTATION_COLOR_READ_FORMAT_OES and
GL_IMPLEMENTATION_COLOR_READ_TYPE_OES. This patch makes it always read
using GL_RGBA and GL_UNSIGNED_BYTE and then convert the results if
neccessary.

This has some room for improvement because it doesn't attempt to use
the implementation specific format. Also the conversion is somewhat
wasteful because there are currently no cogl_bitmap_* functions to
convert without allocating a new buffer so it ends up doing an
intermediate copy.

9750b90f37 cogl-bitmap: Fix converting formats with and without alpha channels
_cogl_bitmap_convert_format_and_premult was failing when converting
from RGBA to RGB and vice versa. _cogl_bitmap_fallback_convert
converts without altering the premult status so when choosing a new
format it would copy over the premult bit. However, it did this
regardless of whether the new format had an alpha channel so when
converting from RGBA_8888_PRE to RGB_888 it would end up inventing a
new meaningless format which would be RGB_888_PRE. This patch makes it
avoid copying the premult flag if the destination has no alpha. It
doesn't matter if it copies when the source format has no alpha
because it will always be unset.

_cogl_bitmap_convert_format_and_premult was also breaking when
converting from RGBA_8888_PRE to RGB_888 because it would think
RGB_888 is unpremultiplied and try to convert but then
_cogl_bitmap_fallback_premult wouldn't know how to do the conversion.

a28440eafb clutter-texture: Remove confusing comments about realization
In 125bded81 some comments were introduced to ClutterTexture
complaining that it can have a Cogl texture before being

so there is no need to wait until the actor is realized before setting
a texture. This patch replaces the comments with clarification that
this should not be a problem.

The patch also changes the documentation about the realized state in
various places to clarify that it is acceptable to create any Cogl
resources before the actor is realized.

716ec82db8 clutter-cairo-texture: Use the new cogl_pixel_buffer API
ClutterCairoTexture now stores the surface image data in a Cogl pixel
buffer object. When clutter_cairo_texture_create is called the buffer
is mapped and a new Cairo surface is created to render directly to the
PBO. When the surface is destroyed the buffer is unmapped and a Cogl
texture is recreated from the buffer. This should enable slightly
faster uploads when using Cairo because it avoids having to copy the
surface data to the texture.

1a1e7d3573 text: Increase the size of the Layout cache
Currently, each ClutterText caches 3 Pango layouts:

  » one for the preferred, unbounded width
  » one for the preferred height for a given width
  » one for the allocated size

Some layout managers do a double pass that could flush the whole cache
before it has a chance of actually storing relevant data, resulting in
a continuous series of misses.

We can try to counteract this by doubling the size of the cache, from
three slots to six. More than six would be pointless, as well as too
memory consuming; but we might get down to a number between 3 and 6 at
any later point.

dd407326fe text: Check generated size of layouts in cache
By comparing the requested size against the computed sized for existing
Pango layouts we can avoid creating layouts where the requested size
matches that of a previously computed one.

In particular this optimisation means that when working with a fixed
positioning based layout (with no constraints on the size of the
ClutterText) the same PangoLayout can be used to calculate the preferred
width, height and also the layout used for the actual painting.

708bbc72e1 cogl: Implement retained clip stacks
This adds three new internal API functions which can be used to retain
the clip stack state and restore it later:

 _cogl_get_clip_stack
 _cogl_set_clip_stack
 _cogl_clip_stack_copy

The functions are currently internal and not yet used but we may want
to make them public in future to replace the cogl_clip_stack_save()
and cogl_clip_stack_restore() APIs.

The get function just returns the handle to the clip stack at the top
of the stack of stacks and the set function just replaces it.

The copy function makes a cheap copy of an existing stack by taking a
reference to the top stack entry. This ends up working like a deep
copy because there is no way to modify entries of a stack but it
doesn't actually copy the data.

a0e19c9469 cogl-clip-stack: Use reference counted stack entries
The stack is now stored as a list of reference counted entries.
Instead of using a GList, each entry now contains a link with a
reference to its parent. The idea is that this would allow copying
stacks with a shared ancestry.

Previously the code flushed the state by finding the bottom of the
stack and then applying each entry by walking back up to the top. This
is slightly harder to do now because the list is no longer
doubly-linked. However I don't think it matters which order the
entries are applied so I've just changed it to apply them in reverse
order.

There was also a restriction that if ever the stencil buffer is used
then we could no longer use clip planes for any subsequent entries. I
don't think this makes sense because it should always work as long as
it doesn't attempt to use the clip planes more than once. I've
therefore removed the restriction.
