Of course, we must pass coordinates in the NSWindow coordinate system
when creating an NSEvent. This fixes drag icon positioning and makes
the icon slide back to the correct position when the drag is
canceled.
Due to the way the tests are structured, a missing libXext will give a
warning about a missing libX11 (even if libX11 is installed). This is
confusing to people who are trying to build Gtk.

Instead of overriding the font theme settings, just set the Pango
attributes we want on the label. This fixes message dialogs growing on
style_update after recent GTK+ changes.
Instead of using 1 global queue for both resizes and style validation,
use 2 queues. This makes the code a lot simpler and fixes a bug where we
could accidentally stop restylying for very delayed restyles.
We now animate the core style information (see comment in
gtk_style_context_save()). A lot of widgets save + set custom style
classes/states during drawing and so can't be animated. It does work for
labels, menus and buttons though.
This is a GtkCssComputedValues subclass. So it's essentially a store for
computed CSS values. But it can be animated by advancing it to a certain
timestamp.
A StyleAnimation is an immutable object used to track the state of CSS
values. I'd have liked to make it fully immutable - ie not have the
timestamp in there - but couldn't find a place to sanely store the
timestamp.
This is an abstract base class. Implementations for this will be added
later (for both CSS3 transitions and animations, potentially for
animated images).
Actually aplying the information in this object will be done by a
different object commtted later.
This has two goals:
1) Move invalidation code out of a nested if branch. Invalidation is
actually the most important thing this function does.
2) Have the changes bitmask available. It will needed for invalidate
calls to children later.
The design principles were:
- synchronized
If multiple style contexts are animating, they should all do an
animation step at the same time.
- degrades well
Even when there's thousands of style contexts all animating at the same
time, the animation steps don't starve the CPU. This is achieved by
making sure the timeout is really fast. It just sets a bunch of flags.
- no hidden bottlenecks
Turning animatability on or off on a style context is O(1).
So far it is unused.
