Make the quartz backend support the new queued translations. We do this
by keeping our own copy of the region that has been set to need display.
Using this region we can intersect by the given area, translate this and also
set needs display for the resulting area.
With Bug 302240, a check was added to avoid keynav to unrealized
radio buttons in the group, but that's not the right check - the
check should be on MAPPED instead, since a widget can be realized
even if it, or a parent, is hidden. Bug 595599
When filtering out the events for "window" from the events we got for
our "impl_window", don't forget to adjust the returned number of
events because it might be smaller than what XGetMotionEvents has
returned, and free coords we allocated too much. Also if we filtered
away *all* events, return FALSE and get rid of the allocated history
entirely. Together fixes all sorts of mishehavior when painting in
GIMP, from coords going wild to plain crashes and infinite loops.
When a SIGPIPE signal is raised during printing with lpr,
application should not be killed by the signal but a standard
error-workflow should be performed (bug #503776).
On startup, the root window got assigned the size of the main screen.
But, the GdkScreen has the width of all screens/monitors connected to the
machine. Change this so that in _gdk_windowing_window_init, we assign
the width/height of all monitors to the root window width, height.
Should fix bug 594738.
The quartz backend simulates the semantics of XGrabPointer, as a part of
this it checks the event mask of the grab. However, implicit grabs on X
do not go through XGrabPointer and thus the quartz backend should not check
the event mask for these. This fixes various "the UI got stuck" cases.
Applications using non-double-buffered drawing using cairo (e.g. Abiword)
can draw directly to the window using cairo and thus manage to avoid
the automatic flushing of outstanding moves. This can cause redraw
inconsistencies like bug 593507.
We fix this by always flushing when exposing non-double-buffered widgets.
If we move, resize or otherwise change a window from inside a (double
buffered) expose handler we can run into issues with double buffered
paints that have already been ended but have not yet been commited
to the window from the implicit paint pixmap.
For instance, any copies of source regions due to a window scroll need
to take these into account, and any operation that causes some drawing at
a destination covered by the implicit paint region would be overdrawn
when the implicit paint is ended.
So, before we do any window-hierarchy changing operation while an implicit
paint is in effect we flush all moves and already commited paints.
