From 40919d7db29d036033f57fe6fbf9e3f562e61c0d Mon Sep 17 00:00:00 2001 From: Jens Arnold Date: Tue, 25 Mar 2008 23:21:36 +0000 Subject: iAudio M3: Optimised LCD driver, with more/better assembly code. Speedup is ~80% when boosted, ~15% when unboosted. Also implemented grey phase blitting. * Adapted the greyscale library, and the plugins using it. * Fixed a bug in greyscale scroll down for vertically packed pixels. git-svn-id:
