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.

So as to avoid breaking the 1.x API or even the ABI since we are quite
late in the 1.16 development cycle the patch was modified to build
cogl-path as a noinst_LTLIBRARY before building cogl and link the code
directly into libcogl.so as it was previously. This way we can wait
until the start of the 1.18 cycle before splitting the code into a
separate libcogl-path.so.
This also adds shims for cogl_framebuffer_fill/stroke_path() to avoid
breaking the 1.x API/ABI.
Otherwise, if we try egl-wayland first, we get the environment

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.
Note: the cogl_framebuffer_draw_primitive() api isn't removed by this
patch so it can more conveniently be cherry picked to the 1.16 branch so
we can mark it deprecated for a short while. Even though it's marked as
experimental api we know that there are people using the api so we'd
like to give them a chance to switch to the new api.

The plan is to remove the cogl-auto-texture apis since they hide a bit
too much from developers but currently the conformance tests depend on
these apis in numerous places.
For the conformance tests it makes some sense to continue using high
level texture apis similar to the auto-texture apis since we may want
to make broad variations to how textures are allocated as part of the
testing running if that might help exercise more code paths.
This patch copies much of the auto-texture functionality into some
slightly more special purpose utilities in test-utils.c/h. Minor changes
include being constrained to the public Cogl api and they also don't
let you catch CoglErrors and just assume they should abort on error.

bitmap that's created for the given file and allow conversions to

converting in place depending on a 'can_convert_in_place' argument.
This ability to convert bitmaps in-place has been integrated across the

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.
The cogl_poll_* functions have been changed so that they can cope if
the pending and dispatch callbacks remove their own FD while they are
invoked.
