[cairo] Bringing back the dead... RGB16_565

[Vladimir Vukicevic]

One issue though is that there is no way to create a 565 image surface, 
even though pixman supports this format.  I don't really know how to 
introduce it just for image surfaces though, since doing so would 
require them to be expanded out to rgb24 if used with another surface 
that can't handle 565 natively.

One option that comes to mind is that 
acquire_source_surface/acquire_dest_surface can pass along a list of 
formats that would be acceptable to the caller, so that the 
conversion/expansion would take place there if necessary.
