Title: GRIM: Greatly improved memory usage of bitmaps

For me, this cuts the amount of memory residual uses by half.

The main way it does this is by only loading the bitmaps that are being drawn. For example, in Manny's office there are 6 backgrounds but the player will usually see at most three when entering the office.
