This is my implementation of some tests from popular 240p test suite
(http://junkerhq.net/xrgb/index.php?title=240p_test_suite). It is still
in early beta so comments and suggestions are welcomed.

Limitation: No overscan in wb prefs please, im still new and cant display
sprites if overscan is present.
