Title: Fix render position of flipped TMX tiles.

This patch does two things:

1. Offsets the transformation matrix by the current level position, fixing flipped tiles on maps that are smaller than the screen resolution.
1. Offsets the transformation matrix again by the viewport position, fixing flipped tiles on maps that are larger than the screen resolution and scrolled.
