We automatically switch the request mode of the container depending on
the GridLayout's orientation, but we need to keep track of the request
mode during allocation, so that we don't get out of sync if the user
changed the request mode after adding the layout manager.
This change also brings us closer to the code in GtkGrid.
We use the orientation of the grid to get the preferred size of the
layout, but we should be using the orientation of the request instead.
The preferred width has an orizontal orientation, and the preferred
height has a vertical orientation.
This allows us to refactor the get_preferred_* implementation into a
separate function.
We are currently using deprecated/Clutter-specific API in Cogl to
retrieve the XVisualInfo associated with the (E)GLX context. Cogl 1.21.2
added new CoglRenderer API to achieve the same result.
We want to use the Cogl GL3 driver, if possible, and then go through a
known list of Cogl drivers, before giving up and using COGL_DRIVER_ANY.
Based on original patch from Emmanuele Bassi.
We have to create and tear down the whole context when trying
out the drivers though because the extension checks do not happen
until cogl_context_init.

The ClutterX11XInputEventTypes enumeration has been unused inside
Clutter for the past 4 years and a half, since we switched to the
XInput 2 API.
The enumeration itself has always been private, and nobody should
have used it in the first place, but if something breaks, we can
revert this commit.
They should be part of the backend-specific API.
The only backend that has an enumeration type is the X11 one, and it's
small, so we can simply put it there.
This is not an ABI change: the backend-specific symbols are still in
the same SO. You'll be required to import clutter-x11.h to have access
to the GType method at the source level, whereas before just importing
clutter.h would have sufficed. The only user of that enumeration was a
function declared in clutter-x11.h, anyway.
We're inconsistently using the NAMESPACE variable instead of passing
the --identifier-prefix and --symbol-prefix command line arguments to
the introspection scanner.
Now that we can warn about deprecated macros, we should finally do it
for the old, non-namespaced key symbol macros that we've been stringing
along since the 1.0 days.
