The recommended usage model for rendering pipelines with minor changes
is to make a copy of a base pipeline just before rendering and then
modify that. The new pipeline can then be used as the base pipeline
for the next paint. Currently this has a known problem when modifying
uniform values in that Cogl won't prune the redundant ancestry and
instead it will end up with an ever-growing chain of pipelines. This
is particularly bad for something like CoglGST where it could also end
up leaking textures for the video frames if the pipelines are used to
render video.
The patch adds a test case for that situation so that we won't forget
about the problem. The test is maked as a known failure. Additionally
the patch adds a similar test for setting the blend constant to
constrast the test with some state that does work correctly.

This reverts the change in semantics for cogl_texture_new_with_size so
that it goes back to allocating textures synchronously and returning
NULL if there was a failure to allocate. Only the new/2.0 texture apis

Previously we would only add the #version pragma to shaders when
point sprite texture coordinates are enabled for a layer so that we
can access the gl_PointCoord builtin. However I don't think there's
any good reason not to just always request GLSL version 1.2 if it's
available. That way applications can always use gl_PointCoord without
having to enable point sprite texture coordinates.
This adds a glsl_version_to_use member to CoglContext which is used to
generate the #version pragma as part of the shader boilerplate. On
desktop GL this is set to 120 if version 1.2 is available, otherwise
it is left at 110. On GLES it is always left as 100.

Mesa has started getting picky about specifying the precision for
floating types in the fragment shader. We already have a default
precision specifier in all the fragment shaders but apparently this
wasn't working because it is only used when the __VERSION__ define is
100 and Mesa is reporting 110. Regardless of whether Mesa is doing the
right thing or not I think it makes sense to use GL_ES instead of
__VERSION__ because we will also need the precision specifier if we
start requesting GLSL 3.0. The GLES specification explictly states
that GL_ES will only be defined for GLES and this is similar to what
the internal meta shaders do in Mesa.

Full GL treats the position attribute specially and requires that it
must be bound to generic attribute location 0 unlike GLES 2.0 or
GL 3.2 core. We now make sure to unconditionally bind the
cogl_position_in attribute to location 0 before linking any glsl program
in cogl.
For reference the relevant part of the GL 3.0 spec that covers these
semantics is Section 2.7 "Vertex Specification" pg 27
After this change there was one remaining problem in
test-custom-attributes where the test_short_verts() test was using its
own "pos" attribute instead of cogl_position_in and so cogl wasn't able
to ensure it would be bound to location 0.
This updates the test to use cogl_position_in but to work around the
fact that glVertexPointer doesn't support UNSIGNED_SHORT components we
force the test to use the glsl backend by setting a shader snippet on

This splits out the cogl_path_ api into a separate cogl-path sub-library

this sub-library disabled if they don't need it which can be useful when
its important to keep the size of an application and its dependencies
down to a minimum. The functions cogl_framebuffer_{fill,stroke}_path
have been renamed to cogl_path_{fill,stroke}.
There were a few places in core cogl and cogl-gst that referenced the
CoglPath api and these have been decoupled by using the CoglPrimitive
api instead. In the case of cogl_framebuffer_push_path_clip() the core
clip stack no longer accepts path clips directly but it's now possible
to get a CoglPrimitive for the fill of a path and so the implementation
of cogl_framebuffer_push_path_clip() now lives in cogl-path and works as
a shim that first gets a CoglPrimitive and uses
cogl_framebuffer_push_primitive_clip instead.

Instead of queuing the frame sync event immediately after a swap, the
Wayland winsys now installs a frame callback and queues the event when
Wayland reports that the frame is complete. It also reports the
COGL_FRAME_EVENT_COMPLETE event at the same time because there is no
more information we can give.
This patch is a bit of a divergence from how the events are handled in
the GLX winsys. Instead of installing its own idle function, the
_cogl_onscreen_queue_event() function has now been made non-static so
that it can be used by the Wayland winsys. The frame callback now just
queues an event using that. The pending_frame_infos queue on the
CoglOnscreen isn't used and instead the CoglFrameInfo is immediately
popped off the queue so that it can be stored as part of the closure
data when the frame callback is set up. That way it would use the
right frame info even if somehow the Wayland callbacks were invoked in
the wrong order and the code is a bit simpler.

Previously if the Wayland socket gets closed then Cogl would ignore
the error when dispatching events which meant the socket would be
constantly ready for reading, the main loop would never go idle and it
would sit at 100% CPU. When Wayland encounters an error it will
actually close the socket which means if something else opened another
file then we might even end up polling on a completely unrelated FD.
This patch makes it remove the FD from the main loop as soon as it
hits an error so that it will at least avoid breaking the main loop.
However I think most applications would probably want to abort in this
case so we might also want to add a way to inform the application of
this or even just abort directly.

This adds cogl_wayland_renderer_set_event_dispatch_enabled() which can
be used to prevent Cogl from adding the socket for the Wayland display
to its list of file descriptors to poll. This can be used in
applications that want to integrate Cogl with existing code that is
reading from the Wayland socket itself.

The Wayland 1.0 protocol supports multiple independent components querying the
available interfaces by retreiving their own wl_registry object so the
application doesn't need to pass them down anymore.

The idea with the framebuffer allocation is that it will lazily
allocate so that if you don't want to handle errors then you don't
have to be aware that there is an allocation step. In order for this
to work any accessors that get data that is only available after
allocation should implicitly allocate the framebuffer. This patch
makes that change for cogl_wayland_onscreen_get_surface and
cogl_wayland_onscreen_get_shell_surface.

cogl_wayland_onscreen_get_surface previously only worked if the
onscreen had a foreign surface on it. However there is no reason why
this shouldn't also work fine for manipulating the surface that Cogl
created as well. We may want to consider adding a separate getter for
the foreign surface that can be used before the framebuffer is
allocated.

CoglFixed was trying to use the __FLOAT_WORD_ORDER macro in order to
do some fast float conversions but it wasn't including any header that
could define it so it was giving an annoying warning. This patch
checks for the macro in endian.h in the configure script and only
checks its value if it's available.

Commit 839cf49763 changed the inline ARM assembler so that it
won't be used when targetting the Thumb instruction set. I manually
applied the patch but I messed up the #if so it was generating a
warning.
