This definitely seems worth experimenting with. big-bang does (can,
really) create bitmaps itself. It gets 2htdp/image images from the
user's program and then it can create a bitmap to draw them into
directly, if it wants to. It may already be creating a bitmap
explicitly, I'm not sure.

Roughly, using the `make-bitmap` method creates a bitmap that's on the
graphics card instead of main memory.
