When scaling part of an image we need to specify the source coordinates
in transformed coordinates. For large magnifications this means
we will get pretty large values.
Now, if e.g. src_x * transform is larger than 32765, then the coordinate
ends up outside the pixman 16bit image size, so the rendering
will not work.
In order to work around this we generate a "sub-image" of the pixman
image such that the src_x/y values we have to specify are zero (or near
zero).
Math is hard, let's go shopping ;)
Seriously: Looks sane to my untrained eyes, ACK.
