- *
- * Future directions:
- *  [X] This does suggest the need for a palletized graphics surface. Thanks kling!
- *  [X] alternate column updates, or vertical interlacing. this would certainly alter
- *      the effect, but the update load would be halved.
- *  [/] scaled blit
- *  [ ] dithering?
- *  [X] inlining rand()
- *  [/] precalculating and recycling random data
- *  [ ] rework/expand palette
- *  [ ] switch to use tsc values for perf check
- *  [ ] handle mouse events differently for smoother painting (queue)
- *  [ ] handle fire bitmap edges better
