-Bug 637828. Reset the transform on the dest image. r=joe
-
-We can get into a situation where the destination image has a transform
-because we use it as source. The transform set when the image is a source
-sticks around and when we use it as a destination pixman gets confused.
-
-It seems like the code at fault here is really pixman. I think that pixman
-should probably not be using a transformed fetch on the destination image under
-any circumstances.
-
-For example, in this case we're fetching destination pixels from a different
-part of the image than we're storing them to. I can't see any reason for
-wanting this behaviour.
-
-However, reseting the transform seemed like the easiest solution.
