c4eb869bd7 framebuffer: expose viewport getters/setters
This exposes experimental cogl_framebuffer APIs for getting and setting
a viewport without having to refer to the implicit CoglContext. It adds
the following experimental API:

  cogl_framebuffer_set_viewport
  cogl_framebuffer_get_viewport4fv
  cogl_framebuffer_get_viewport_x
  cogl_framebuffer_get_viewport_y
  cogl_framebuffer_get_viewport_width
  cogl_framebuffer_get_viewport_height

2282455f27 wayland: Allow setting foreign display/compositor
To support toolkits targeting wayland and using Cogl we allow toolkits
to be responsible for connecting to a wayland display and asking Cogl to
use the toolkit owned display and compositor object. Note: eventually
the plan is that wayland will allow retrospective querying of objects so
we won't need the foreign compositor API when Cogl can simply query it
from the foreign display.

442d4586b7 win32: Use the right macro name for COGL_HAS_WIN32_SUPPORT
Some places were using COGL_HAS_WIN32 but the only macro defined is
COGL_HAS_WIN32_SUPPORT. The similar macros such as COGL_HAS_XLIB are
only defined for compatibility with existing code but COGL_HAS_WIN32
was never defined so there's no need to support it.

One of the places was including the non-existant cogl-win32.h. This
has been removed because the file only temporarily existed during
development of the backend.

6c23f27801 Adds a way for Cogl to control event_mask of foreign wins
This extends cogl_onscreen_x11_set_foreign_xid to take a callback to a
function that details the event mask the Cogl requires the application
to select on foreign windows. This is required because Cogl, for
example, needs to track size changes of a window and may also in the
future want other notifications such as map/unmap.

Most applications wont need to use the foreign xwindow apis, but those
that do are required to pass a valid callback and update the event mask
of their window according to Cogl's requirements.

97243ad9ac Adds cogl_onscreen_show/hide functions
This adds Cogl API to show and hide onscreen framebuffers. We don't want
to go too far down the road of abstracting window system APIs with Cogl
since that would be out of its scope but the previous idea that we would
automatically map framebuffers on allocation except for those made from
foreign windows wasn't good enough. The problem is that we don't want to
make Clutter always create stages from foreign windows but with the
automatic map semantics then Clutter doesn't get an opportunity to
select for all the events it requires before mapping. This meant that we
wouldn't be delivered a mouse enter event for windows mapped underneath
the cursor which would break Clutters handling of button press events.

2a150003ad add missing name mangle for cogl_onscreen_set_swap_throttled
We weren't mangling cogl_onscreen_set_swap_throttled to give it an _EXP
postfix to clarify that it is an experimental symbol.

2bbb0d895b Make cogl_framebuffer_get_width/height experimental public API
It's generally useful to be able to query the width and height of a
framebuffer and we expect to need this in Clutter when we move the
eglnative backend code into Cogl since Clutter will need to read back
the fixed size of the framebuffer when realizing the stage.

d40cdfa3e1 Moves all GLX code down from Clutter to Cogl
This migrates all the GLX window system code down from the Clutter
backend code into a Cogl winsys. Moving OpenGL window system binding
code down from Clutter into Cogl is the biggest blocker to having Cogl
become a standalone 3D graphics library, so this is an important step in
that direction.
