quartz: Ignore events from all mouse buttons past the resize boundary

Browse Source 
Before, right click events were still let through into GDK. In this
case, also middle/right button events with x-coordinates in the range
[-3, 0] are processed, resulting in failures/crashes in the window
finding code because no GdkWindows are present in this range.
