This removes cogl_framebuffer_get_color_format() since the actual
internal format isn't strictly controlled by us. CoglFramebuffer::format
has been renamed to ::internal_format to make it clearer that it only
really represents the premultiplication status.
The plan is to make most of the work involved in creating a texture
happen lazily when allocating so this patch also changes
_cogl_framebuffer_init() to not take a format argument anymore since we
won't know the format of offscreen framebuffers until the framebuffer is
allocated, after the corresponding texture has been allocated. In the
case of offscreen framebuffers we now update the framebuffer
internal_format during allocation.

This reverts commit bc41489336.
The reason this was causing problems for Clutter is that it defines
COGL_ENABLE_EXPERIMENTAL_2_0_API which is meant to cause the Cogl
headers not to declare the deprecated API. The reverted patch moved
some additional clipping API to a deprecated header which was
previously being used by Clutter. Clutter was still successfully
compiling but with some warnings for the missing function
declarations. However when the binary is run the clipping would get
completely messed up because it would assume all of the arguments to
the functions are integers instead of floats and the wrong values
would be passed.
Clutter now has commit to make it use the 2.0 API instead of the
deprecated functions so the revert is no longer necessary.

On the 1.18 branch this function is deprecated and the documentation

This reverts commit af480a2b8b.
Previously the private feature flags were stored in an enum and we
already had 31 flags. Adding the 32nd flag would presumably make it
add -2³¹ as one of the values which might cause problems. To avoid
this we'll just use an fixed-size array of longs and use indices for
the enum values like we do for the public features.
A slight complication with this is in the CoglDriverDescription where
we were previously using a static intialised value to describe the set
of features that the driver supports. We can't easily do this with the
flags array so instead the features are stored in a fixed-size array
of indices.

This declares the interface types CoglFramebuffer, CoglBuffer,
CoglTexture, CoglMetaTexture and CoglPrimitiveTexture as void when
including the public cogl.h header so that users don't have to use lots
of C type casts between instance types and interface types.
This also removes all of the COGL_XYZ() type cast macros since they do
nothing more than compile time type casting but it's less readable if
you haven't seen that coding pattern before.
Unlike with gobject based apis that use per-type macros for casting and
performing runtime type checking we instead prefer to do our runtime
type checking internally within the front-end public apis when objects
are passed into Cogl. This greatly reduces the verbosity for users of
the api and may help reduce the chance of excessive runtime type

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

right thing or not I think it makes sense to use GL_ES instead of

that GL_ES will only be defined for GLES and this is similar to what

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
the pipeline.

This splits out the cogl_path_ api into a separate cogl-path sub-library
like cogl-pango and cogl-gst. This enables developers to build Cogl with
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.
We may want to consider renaming cogl_framebuffer_push_path_clip to
put it in the cogl_path_ namespace.

When splitting out the CoglPath api we saw that we would be left with
inconsistent drawing apis if the drawing apis in core Cogl were lumped
into the cogl_framebuffer_ api considering other Cogl sub-libraries or
that others will want to create higher level drawing apis outside of
Cogl but can't use the same namespace.
So that we can aim for a more consistent style this adds a
cogl_primitive_draw() api, comparable to cogl_path_fill() or
cogl_pango_show_layout() that's intended to replace
cogl_framebuffer_draw_primitive()
Note: the attribute and rectangle drawing apis are still in the
cogl_framebuffer_ namespace and this might potentially change but in
these cases there is no single object representing the thing being drawn
so it seems a more reasonable they they live in the framebuffer
namespace for now.

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.

Previously Cogl would only call wl_display_flush after doing a swap
buffers on the onscreen because that is the only place where Cogl
itself would end up queueing requests. However since commit
323fe188748 Cogl takes control of calling wl_display_dispatch as well
which effectively makes it very difficult for the application to
handle the Wayland event queue itself. Therefore it needs to rely on
Cogl to do it which means that other parts of the application may also
queue requests that need to be flushed.
This patch tries to copy the display fd handling of window.c in the
Weston example clients. wl_display_flush will always be called in
prepare function for the fd which means it will always be called
before going idle. If flushing the display causes the socket buffer to
become full, it will additionally poll for write on the FD to try
flushing again when it becomes empty.
We also need to call wl_display_dispatch_pending in the prepare
because apparently calling eglSwapBuffers can cause it to read data
from the FD to receive events for a different queue. In that case
there will be events that need to be handled but the FD will no longer
be ready for reading so we won't wake up the main loop any other way.

Previously on GLES2 where there is no builtin point size uniform then
we would always add a line to the vertex shader to write to the
builtin point size output because when generating the shader it is not
possible to determine if the pipeline will be used to draw points or
not. This patch changes it so that the default point size is 0.0f
which is documented to have undefined results when drawing points.
That way we can avoid adding the point size code to the shader in that
case. The assumption is that any application that is drawing points
will probably have explicitly set the point size on the pipeline
anyway so it is not a big deal to change the default size from 1.0f.
This adds a new pipeline state flag to track whether the point size is
non-zero. This needs to be its own state because altering it needs to
cause a different shader to be added to the pipeline cache. The state
flags that affect the vertex shader have been changed from a constant
to a runtime function because they will be different depending on
whether there is a builtin point size uniform.
There is also a unit test to ensure that changing the point size does
or doesn't generate a new shader depending on the values.
