Andrew Mahone 92785b8f2f Use pre-multiplication in scaler to save one multiply per color component on ARM and Coldfire, at the cost of an extra add/shift in the horizontal scaler to reduce values to a workable range. SH-1 retains the same basic math, as ... the use of 16x16->32 hardware multiplication in the earlier scaler stages saves more than removing the 32x32->40 multiply to descale output. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21091 a1c6a512-1295-4272-9138-f99709370657		2009-05-26 20:00:47 +00:00
