/*
GP2X minimal library v0.5 by rlyeh, 2005.
+ GP2X video library with double buffering.
+ GP2X soundring buffer library with double buffering.
+ GP2X joystick library.
Thanks to Squidge, Robster, snaff and NK, for the help & previous work! :-)
What's new
==========
0.5: patched sound for real stereo (using NK's solution); better init code.
0.4: lots of cleanups; sound is threaded now, double buffered too; 8 bpp video support; better exiting code.
0.3: shorter library; improved joystick diagonal detection.
0.2: better code layout; public release.
0.1: beta release
