Cairo computes bounds wrong in imageSurfaceGetPixels

Reported by: guest Owned by: paolo
Priority: normal Milestone: 0.13.0
Component: Cairo bindings Version: 0.12.4

Description

r in imageSurfaceGetPixels is the stride of the surface, which is defined as being the number of bytes of one row. Therefore, bytes can just be computed by r * height. Also, if I understand correctly, the + 7 should have been outside the row computation to force rounding upwards.

Further more, the bounds in mkSurfaceData seem to be off by one.

Please see attached patch.
