[mythtv] [PATCH] OSD constant LUT

[Andrew Mahone]

The attached patch replaces the replaces the pow_lut table in OSDSurface with 
a precalculated, constant table.  This adds 64kB to the size of libmythtv, 
but saves the same amount per OSDSurface instance, and should be faster for 
multiple instances because there won't be more than one copy of the table 
that the CPU is trying to cache (I have no idea how many OSDSurfaces 
typically exist at once).  Sharing a single table everywhere should be safe, 
as the table is never written to.  Sorry for the compressed patch, but the 
lut.c file is around .4MB.
