face is the new face to set. if clear is set, clear this face. If not set, don't clear. the reason clear may not be set is because this is an animation update - animations must all be the same size, so when we set the data for the space, we will just overwrite the old data. Problem with clearing is that clobbers the animation data.

Check if current map position is out of bounds if shifted by (dx, dy).

If so, shift the virtual map so that the map view is within bounds again.

Assures that [pl_pos.x-MAX_FACE_SIZE..pl_pos.x+MAX_VIEW+1] is within the bounds of the virtual map area. This covers the area a map1a command may affect plus a one tile border.
