- Fix crash on window close
- Qt expects the QWidget to remain available even after it has
processed a close event. So, use deleteLater() instead of
deleting outright.
- Also carry around the MozQWidget pointer (though we need to rework
CreateQWidget and ::Initialize) so that we can call dropReceiver
- Fix screen <-> widget coordinate translation
- Fixes popup menu positioning
- Honor mayWait in nsAppShell::ProcessNextNativeEvent
- Prevents massive busy-waiting
- Don't pretend to support translucent windows
- Fix embedding widget build failure
- cairo-qpainter: invert source matrix in paint() to get proper
transform (proper positioning of elements drawn using paint())
- Cleaner event handling in mozqwidget -- return full nsEventStatus,
not just boolean, and decide whether to call QWidget::event() based
on that.
