The first two are true according to my understanding. For the third I am
not really sure. We should add some log statements in the class
CairoContext and monitor in which order the following methods get called
during resize and whether the correct surface object gets used:

+ (void) handleExposeRect: (NSRect)rect forDriver: (void *)driver
- (void) GSSetDevice: (void *)device : (int)x : (int)y

Hope this helps,
