Core: A graphics framework can now register a hook function to extend the core screendump routine. * Grayscale library: (1) Changed the screendump routine into a hook, and implemented it for H1x0. (2) The planar pixel setting routines now use one register less. Fixes build problem with developer builds (frame pointers enabled) on coldfire.
