commit ab51ab22f2f0150abb419fd1c832f5367bb79b5e
Author: Ronald G. Minnich <rminnich at google.com>
Date: Tue Mar 5 13:32:24 2013 -0800
link/graphics: implement a palette setting operator
Add a new operator, P, for the state machine, meaning
implement a palette fill.
Implement a function (palette) that fills the palette when the
P operator is hit.
This replaces 256 lines in the state machine table with 1.
