Fixed the last (?) glitches around the mouse cursor [*] in aspect-ratio

correction mode by making sure that dirty rects always start on a line
that won't have its colours changed by the stretching function. This was
probably only noticeable when using the 1x scaler.

[*] Actually, the glitches weren't specific to the mouse cursor, but it was
    useful for triggering them.
