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.

There was a circular depedency when building from a fresh git clone

test-fixtures also indirectly includes cogl-enum-types.h which is only

just include specific cogl headers instead of cogl/cogl.h then we can

The Wayland server API has changed so that wl_shm_buffer is no longer

resource.
cogl_wayland_texture_2d_new_from_buffer now takes a resource pointer

depending on whether it can get a wl_shm_buffer out of the resource
instead of trying to query the buffer type.
Cogland has also been updated so that it tracks a resource for buffers
of surfaces instead of directly tracking a wl_buffer. This are pointed
to by a new CoglandBuffer struct which can be referenced by a
CoglandBufferReference. The WL_BUFFER_RELEASE event will be posted
when the last reference to the buffer is removed instead of directly
whenever a new buffer is attached. This is similar to how Weston

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, when CoglGST generated the default sampling snippet it
would set the replace string so that Cogl wouldn't generate any
redundant code for the other layers. However this also meant that it
wouldn't modulate with the default colour. This patch changes it to
set the combine mode on all of the layers to REPLACE(PREVIOUS) so that
it just copies the previous layer without generating any texture
sampling. That way the fragment snippet for the final layer can just
modulate the previous value with the video sampling function. This
makes it possible to set a color on the pipeline and have it modulate
the video. Also if we eventually add a way to insert layers before the
GST sampling layer then it can modulate with those.

Without understanding how the experimental api is implemented it seems

passing that to some unknown gstreamer code which would presumably
somehow have to use the same GL context as Cogl to be able to do

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.
