Fix rounding error with tiled bitmap draws
We were snapping the top-left of the destination rectangle to integers,
but using the original (fractional) size. This led to us losing rows or
columns of pixels at the first tile boundary.
Also added a GM that demonstrates the bug (now renders correctly).
