 //      scaling the image down by the matrix' scale
 //  The bug was that for cases like this, we were incorrectly trying to take a
 //  fast-path in the bitmapshader, but ended up drawing the last col of pixels
 //  twice. The fix resulted in (a) not taking the fast-path, but (b) drawing
 //  the image correctly.
