061240ef2a 2d-sliced: add _new_from_file/data/bitmap apis
This adds cogl_texture_2d_sliced_new_from_bitmap/data/file apis in
preparation for removing the cogl_texture_new_from_bitmap/file apis that
are considered a bit too magic, but we don't want to loose the
convenience they have.

fc5d1a8a68 Expose CoglAtlasTexture api
This exposes the CoglAtlasTexture api, making the following public:
cogl_atlas_texture_new_with_size
cogl_atlas_texture_new_from_file
cogl_atlas_texture_new_from_data
cogl_atlas_texture_new_from_bitmap

The plan is to remove auto-texture apis like cogl_texture_new_from_file
since they are a bit too magic, but that means we need an explicit way
for users to allocate texture that will go in the atlas.

Although the _new_from_file() api is arguably redundant since you can
use _bitmap_new_from_file() followed by _atlas_texture_new_from_bitmap()
we don't want to loose any of the convenience that
cogl_texture_new_from_file() had.

6f480c7530 texture: remove _cogl_texture_prepare_for_upload
This removes the gl centric _cogl_texture_prepare_for_upload api from
cogl-texture.c and instead adds a _cogl_bitmap_convert_for_upload() api
which everything now uses instead. GL specific code that needed the gl
internal/format/type enums returned by _cogl_texture_prepare_for_upload
now use ->pixel_format_to_gl directly.

Since there was a special case optimization in
cogl_texture_new_from_file that aimed to avoid copying the temporary
bitmap that's created for the given file and allow conversions to
happen in-place the new _cogl_bitmap_convert_for_upload() api supports
converting in place depending on a 'can_convert_in_place' argument.

This ability to convert bitmaps in-place has been integrated across the
different components as appropriate.

In updating cogl-texture-2d-sliced.c this was able to remove a number of
other GL specific parts to how spans are setup.

4d5af45d99 cogl-gst: adds _sink_is_ready() api

check if it's safe to call cogl_gst_video_sink_get_pipeline() or

Normally an application can listen for the pipeline-ready signal but
sometimes a sink can be passed between components that didn't have an
opportunity to connect a signal handler, so they need a way to
directly check the status.

b3cc4d26d9 wayland: Send COGL_FRAME_EVENT_SYNC based on the frame callback
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.

737806bcee wayland: Remove the Wayland socket FD if there are any errors
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.

8911da794e Implicitly allocate on cogl_wayland_onscreen_get_(shell_)?surface

allocate so that if you don't want to handle errors then you don't

to work any accessors that get data that is only available after
allocation should implicitly allocate the framebuffer. This patch

b1542cf9dd Don't include cogl/cogl.h from test-utils.h
There was a circular depedency when building from a fresh git clone
where test-fixtures needs to be built before the cogl directory, but
test-fixtures also indirectly includes cogl-enum-types.h which is only
generated when building the cogl directory. If we change the header to
just include specific cogl headers instead of cogl/cogl.h then we can
break the circular dependency.

This needs a tweak to test-no-gl-header because that first undefines
COGL_COMPILATION before including test-utils.h. However it doesn't
really do any actual work so we can get away without including it.

1ad0e81b7b wayland-server: Update because wl_shm_buffer is no longer a wl_buffer
The Wayland server API has changed so that wl_shm_buffer is no longer
a type of wl_buffer and it instead must be retrieved directly from the
resource.

cogl_wayland_texture_2d_new_from_buffer now takes a resource pointer
instead of directly taking a wl_buffer and it will do different things
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
works.

baa398b324 wayland: Always call wl_display_flush before going idle
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.

2f4d66f950 Don't create a layer when enabling texture coordinate attributes
When a primitive is drawn with an attribute that contains texture
coordinates Cogl will fetch the corresponding layer in order to
determine the unit number. However if the pipeline didn't actually
have a layer it would end up redundantly creating it. It's probably
not a good idea to be modifying the pipeline while flushing the
attributes state so this patch makes it pass the no-create flag to the
get_layer function and then skips out enabling the attribute if the
layer didn't already exist.

e926c1dab4 Fix the alpha value in the default texture data
When a layer is added to a pipeline without setting a texture it ends
up sampling from a default 1x1 texture which is meant to be solid
white. However for some reason we were creating the texture with 0
opacity which is effectively an invalid premultiplied colour. This
would make the blending behave oddly if it was used.

7b80ddcef9 Log a fatal error when an error is propagated to a NULL error argument
Unlike in GError, the policy in Cogl for when NULL is passed as the
CoglError argument is that the program should abort with a fatal
error. Previously however any errors that were being propagated were
being silently dropped if the application passed NULL. This patch
fixes it to also log a fatal error in that case.

5faed43f29 cogl-gst: expose aspect ratio apis
This adds several utility apis that aim to make it as easy as possible
for an application to determine what size a video should be drawn at.

The important detail here is that these apis take into account the
pixel-aspect-ratio in addition to the video's own aspect ratio.

This patch updates the cogl-basic-video-player example to use the
cogl_gst_video_sink_fit_size() api to perform letterboxing.

ee559d4e93 cogl-gst: Remove the return value from attach_frame()
Previously cogl_gst_video_sink_attach_frame returned the last layer
used by the sink. This can also be retrieved via
cogl_gst_video_sink_get_free_layer so I don't think it's necessary to
return it here and it seems kind of out of place.
