1 What's not implemented (and should be)
2 --------------------------------------
5 - blit bitmaps (should respect rotation and pixel formats)
7 - loading bitmaps from image files (jpg, png, bmp, pnm ...)
11 - finish framebuffer backend (SDL does not work on most of my framebuffers)
12 - other than SDL X backend (SDL does support only one window)
13 - some overall initialization routines
14 - backed event handling
16 * Meditate about bit endians and why these aren't separate pixel types
17 (which would make our lives a bit easier)
27 - drawing with alpha channel
