Cairo fix of getImageData

[CAIRO] getImageData fails on a given rect bigger than the image rect.

I found this bug during my work on SVG feGaussianBlur. Currently only canvas
could test it, but we don't allow the it there to make a bigger rect then the
image rect.
The problem is, that the destination image and source image were mixed up on
creating the imageData. This patch just follows to the behavior of the other
ports.
