	* app/core/gimpdrawable-transform.c
	(gimp_drawable_transform_tiles_affine): factored out new function
	gimp_transform_region() that contains all the actual transform
	magic, doesn't use a GimpDrawable, and transforms into a passed
	PixelRegion. Will be used for perspective clone after some more
	changes.
