/* Fire.cpp - a (classic) graphics demo for Serenity, by pd.
* heavily based on the Fabien Sanglard's article:
* http://fabiensanglard.net/doom_fire_psx/index.html
*
* 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
