8632c65e79 wayland: Add a cogl_wayland_onscreen_resize function
This function will call into the Wayland EGL platform API and resize the
surface that the window is using and update the internal dimensions for
framebuffer and viewport to reflect the change.

e28db24f7d cogl-crate: Optionally use the swap buffers notify mechanism
If the swap buffers notify mechanism is advertised then the crate
example will now register a callback for it and call g_poll with the
proper timeout from cogl_context_begin_idle instead of trying to

cbbac5a2f5 Add a feature ID for the swap event notification
Previously the swap event notification feature was only accessible as
a winsys feature using the semi-internal
cogl_clutter_winsys_has_feature. This just adds a feature ID for it so
it can also be accessed via cogl_has_feature.

c6528c4b6c Start removing _EXP defines and improves some docs
Originally we decided to use #define tricks to rename all experimental
symbols so that they had an _EXP suffix so it would be a bit clearer for
those wanting to check for ABI changes that they shouldn't worry about
these experimental symbols.

We feel now though that the defines are a bit more hassle than they are
really worth, since they are one extra thing to remember when coding,
they make using gdb slightly more awkward since you have to use the real
symbol name to set breakpoints and we already have a mechanism for
declaring symbols as experimental via gtk-doc that can be used by anyone
wanting to check for ABI changes.

Instead of just using a script to remove all the #defines we are going
to go through them manually because we need to make sure the symbols
are marked as unstable via gtk-doc. This patch does a first batch of
define removals and in fact some of the symbols didn't have any
documentation at all so that needed to be added too.

3bc70687ac Remove old fallback for vblank wait via manual drm ioctl
This workaround code has just been incrementally carried forward since
Cogl was integrated with Clutter but really we have no idea when this
code path was ever tested. Since the work around is from before the time
of the current Cogl developers we don't know anything about the
circumstances which led to this extreme workaround instead of pushing to
fix a driver.

It seems pretty likely we can push to fix any drm based drivers so
we're removing the workaround.

6731569c18 Update all of the examples to use cogl_poll_get_info
The aim is that it should be a requirement that all Cogl applications
hook their mainloops into Cogl so we should lead by examples. Most of
the examples now just call cogl_poll_get_info and then g_poll with a
zero timeout so that they can continue to constantly redraw.

The SDL example is a bit special because SDL makes it very difficult
to wait on either a timeout or any file descriptors. The SDL winsys is
documented not to require blocking on any file descriptors so we can
ignore that. It implements the timeout by adding an SDL timer which
pushes an event to the queue to wake up SDL_GetEvent.

The Cogland example was already using the glib main loop so that one
has been updated to add the CoglGLibSource to it.

85d79ab4fa Add a utility to make a GSource out of a CoglContext
The GSource is created using cogl_glib_source_new which takes a
pointer to a CoglContext. The source calls cogl_poll_get_info() in its
prepare function and cogl_poll_dispatch() in its dispatch
function. The poll FDs on the source are updated according to what
Cogl reports.

The header is only included and the source only compiled if Cogl is
configured with GLib support.

181b875a3d xlib: Internally retrieve XEvents
Previously we relied on the application to send all X events through
Cogl using cogl_xlib_renderer_handle_event. This breaks the
abstraction that an application shouldn't need to know what winsys
Cogl is using. Now that we have main loop integreation in Cogl, the
Xlib-based winsys's can report that Cogl needs to block on the file
descriptor of the X connection and it can manually handle the
events.

The event retrieval can be disabled by an application if it calls the
new cogl_xlib_renderer_set_event_retrieval_enabled() function. The
event retrieval will also automatically be disabled if the application
sets a foreign display.

7497475295 Add support for main loop integration
This adds two new functions:

void
cogl_poll_get_info (CoglContext *context,
                    CoglPollFD **poll_fds,
                    int *n_poll_fds,
                    gint64 *timeout);

void
cogl_poll_dispatch (CoglContext *context,
                    const CoglPollFD *poll_fds,
                    int n_poll_fds);

The application is expected to call the first function whenever it is
about to block to go idle, and the second function whenever it comes
out of idle. This gives Cogl winsys's the ability poll file
descriptors for events. For example when handing swap complete
notifications, it can report that it needs to block on a file
descriptor.

The two functions are backed by winsys virtual functions. There are
currently no implementations. The default handler for get_info just
reports no file descriptors and an infinite timeout.

Since eglGetProcAddress can not be used to query core client APIs

616d27f169 cogl-texture-2d: Fix checking for the EGL winsys
CoglTexture2D had an assert to verify that the EGL winsys was being
used. This doesn't make any sense any more because the EGL winsys
can't be used directly but instead it is just a base winsys for the
platform winsys's. To fix this this patch adds a set of 'criteria'
flags to each winsys, one of which is 'uses EGL'. CoglTexture2D can
use this to determine if the winsys is supported.

Eventually we might want to expose these flags publically so that an
application can select a winsys based on certain conditions. For
example, an application may need a winsys that uses X or EGL but
doesn't care exactly which one it is.
