Since framebuffer state is not flushed prior to replaying the journal,
the trick of marking the framebuffer dirty prior to calling
glBindFramebuffer() doesn't work... the outstanding journal entries
will get replayed to the newly created framebuffer.
Fix this by flushing the journal as well.

In clutter_cairo_texture_create_region it tries to destroy the old
texture before mapping the PBO by setting the texture on the first
layer of the material to COGL_INVALID_HANDLE. However it was using the
material API incorrectly so it ended up showing a warning and doing
nothing.
Instead of asking gtester to run ./test-conformance directly we now tell
it to run a list of wrapper scripts. This results in each test being
spawned in a separate process avoiding leakage of state between tests
which has been a big problem with the conformance tests for quite a
while now.
Otherwise it seems that rounding errors will cause the fragments at
the edge of the quad to blend with neighbouring quarters of the
texture which cause the test to fail.
A few of the tests connected to the paint signal but never
disconnected it. Most of these handlers had a call to g_main_quit in
them which meant that it could sometimes cause subsequent tests to
exit after the first frame is painted. Most of the tests don't
validate any of the results until after a couple of frames have been
rendered so this ended up skipping out the test entirely.
To workaround this the test setup function now disconnects all
handlers for the paint signal on the default stage before the test is
run.
The on_paint function for test-cogl-readpixels tries to temporarily
set the projection, modelview and viewport to its own values. However
it was never restoring the saved values so it could affect the results
of subsequent tests.
If the clip stack is empty then _cogl_clip_stack_flush exits
immediately. This was missing out the assignment of *stencil_used_p at
the bottom of the function. If a path is then used after the clip is
cleared then it would think it needs to merge with the clip so the
stencil would not be cleared correctly.
The code for implementing ClutterColor as GParamSpec and the
color↔string transformation functions were assuming that ClutterColor
owns the data in the GValue struct and directly reading
data[0].v_pointer to get a pointer to the color. However ClutterColor
is actually a boxed type and the format of the data array is meant to
be internal to GObject so it is not safe to poke around in it
directly. This patch changes it to use g_value_get_boxed to get the
pointer.
Also, boxed types allow a NULL value to be stored and not all of the
code was coping with this. This patch also attempts to fix that.

ClutterColor has long had a GTypeValueTable struct around and the
functions defined to be implemented as a fundamental type. However the
struct was never actually used anywhere and ClutterColor is actually
defined as a boxed type. This patch removes the table because it is
very confusing to have code lying around that is not used.

Duplicate the existing ease-in/interpolation mode for the property when
removing, replacing the first key for a property or adding a new first
key for a property.
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.
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.

In 91cde78a7 I accidentally changed the function names that get looked
up for the framebuffer extension under GLES so that they didn't have
any suffix. The spec for extension specifies that they should have the
OES suffix.
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.

Debugging code is not meant to be run in the nominal code path. Use
G_UNLIKELY to be reduce the number of bubbles in the instruction
pipeline.
Took the opportunity to re-indent the macros.
Whether events come from the main loop source or from
clutter_x11_handle_event(), we need to feed them to the backend
virtual handle_event function. This fixes problems with clients
using clutter_x11_handle_event() hanging because
GLXBufferSwapComplete events aren't received.

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.
http://bugzilla.openedhand.com/show_bug.cgi?id=2059
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.

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'.

The warning displayed when too many layers are used had an off-by-one
error so that it would display even if exactly the maximum number is
used. There was also a missing space at the end of the line in the
message which looked wrong when displayed on the terminal.

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.

The ClutterCrossingEvent data structure contains the coordinates
of the crossing; they are regularly filed out by Clutter and by
the backend event processing code. And yet clutter_event_get_coords()
returns (0, 0) because it thinks that CLUTTER_ENTER and CLUTTER_LEAVE
events do not have coordinates.
Whenever we are warning inside ClutterActor we prefer the actor's name
to its type, if the name is set. The current code is made less readable
by the use of the ternary operator:
priv->name != NULL ? priv->name : G_OBJECT_TYPE_NAME (self)
This looks like a job for a simple convenience function.
The script now writes out a separate script that can be used to set up
the build environment to $ROOT_DIR/share/env.sh. This can be sourced
in a shell to set up the build environment or it can be given a
command to directly execute in the environment. This makes it easier
to build Clutter from your own source rather than checking it out from
git directly.
This updates to the latest binaries from Tor Lillqvist. zlib and iconv
are now taken from the Tor deps instead of the gnuwin32 project. SDL
is no longer downloaded because the SDL backend has been removed from
Clutter. The GL headers are downloaded from the Mesa cgit rather than
downloading the whole Mesa package. glext.h is taken directly from
khronos.org.
cogl_path_arc_rel was never in any public headers so it isn't part of
the public API. It also has a slightly inconsistent name because the
rest of the relative path functions are called cogl_path_rel_*. This
patch makes it static for now to make it more obvious that it isn't
public. The name has changed to _cogl_path_rel_arc.
Timers and counters might not exist, so make every section of the
profile report depend on the object that it is querying.
This fixes the profile report generation that was broken by commit
8146d8d08d.
For internal use we should have a get_stage_internal() variant that
avoids type checks and calls to public functions. The implementation
is trivial enough, and it will avoid (scene graph depth + 1) type
checks and (scene graph depth) function calls.
If a path is copied and then appended to, the copy needs to have the
last sub path truncated so that it fits in the total path size in case
the original path was modified. However the path size check was broken
so if the copied path had more than one sub path it would fail.
This changes the original tests so that it splits the original path
into two sub paths. When adding a new block to the copied path it also
adds another sub path. This further stresses the path copying
mechanism and exposes a bug.
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.
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.

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.

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.
