GdkKeymap already has support for _get_num_lock_state() and
_get_caps_lock_state(). Adding _get_scroll_lock_state() would be good
for completness and some backends (Windows?) could take advantage of
this.
The existence of OpenGL implementations that do not provide the full
core profile compatibility because of reasons beyond the technical, like
llvmpipe not implementing floating point buffers, makes the existence of
GdkGLProfile and documenting the fact that we use core profiles a bit
harder.
Since we do not have any existing profile except the default, we can
remove the GdkGLProfile and its related API from GDK and GTK+, and sweep
the whole thing under the carpet, while we wait for an extension that
lets us ask for the most compatible profile possible.
https://bugzilla.gnome.org/show_bug.cgi?id=744407
Now that we have a two-stages GL context creation sequence, we can move
the profile to a pre-realize option, like the debug and forward
compatibility bits, or the GL version to use.
We should remove the mir and cairo surface before rendering the
transient_for, which will regenerate the cairo surface anyways.
Otherwise, we end up releasing both, when we only really want to get rid
of the mir surface.
Mouse over a parent menu[bar] didn't work while the menu was open.
The fix was to correct the behaviour of pointer crossing events so that
the pointer appears to be only inside one window at a time.
See: http://tronche.com/gui/x/xlib/events/window-entry-exit/normal.html
We need this because it fixes menu activation. The menu activation code
looks at the time between events to determine if mouse clicks happen too
quickly.
It's unused. At the same time, rename "begin_paint_region" to
"begin_paint". This will help us clean up how GDK painting works
in the future to allow more creative use of double-buffering.
