Improve enter/motion notify semantics On X11 we receive enter notify and motion notify events for a window regardless of its focus state. On Mac OS X this is not the case. This commit improves the semantics to overcome this difference. It improves on my earlier patch that sent a motion notify event when a window became main. Instead of sending a motion notify when a window becomes main, we now send one when a window becomes key, which comes closest to a window getting focus in X11. This motion notify is needed because Mac OS X does not send motion events when an application is inactive (none of its windows have focus), these events are sent in X11. This dummy motion notify event (with current coordinates of the mouse cursor) allows an application to get its prelight and other state right when it gets focus and thus user attention. Another change is to send an enter notify event when updating the tracking rectangle of a GdkQuartView and the mouse cursor is currently in this rectangle. This rectangle is at least updated on window creation. This enter notify event is important for the case where a new window appears right below the mouse cursor. The window has to receive an enter notify event for the subsequent events to be processed correctly. Mac OS X does not send one in this case, so we generate it ourselves. Both of these synthesized events have to go through _gdk_windowing_got_event() for updating statekeeping, etc. append_event() has a boolean flag now to make this convenient.

Improve enter/motion notify semantics On X11 we receive enter notify and motion notify events for a window regardless of its focus state. On Mac OS X this is not the case. This commit improves the semantics to overcome this difference. It improves on my earlier patch that sent a motion notify event when a window became main. Instead of sending a motion notify when a window becomes main, we now send one when a window becomes key, which comes closest to a window getting focus in X11. This motion notify is needed because Mac OS X does not send motion events when an application is inactive (none of its windows have focus), these events are sent in X11. This dummy motion notify event (with current coordinates of the mouse cursor) allows an application to get its prelight and other state right when it gets focus and thus user attention. Another change is to send an enter notify event when updating the tracking rectangle of a GdkQuartView and the mouse cursor is currently in this rectangle. This rectangle is at least updated on window creation. This enter notify event is important for the case where a new window appears right below the mouse cursor. The window has to receive an enter notify event for the subsequent events to be processed correctly. Mac OS X does not send one in this case, so we generate it ourselves. Both of these synthesized events have to go through _gdk_windowing_got_event() for updating statekeeping, etc. append_event() has a boolean flag now to make this convenient.
