add special matrixprocs when the matrix is at most translate. These are faster

(somewhat) than their scale counterparts, but are also numerically exact for
any size bitmaps. The scale versions, because they operate in a scaled 65535
space, are not always exact for large images (due to SK_Fixed1 / width) loss of
bits
