Details

This patch allows pictureflow to be used on greyscale (but not mono) targets using greylib, and the new greylib scaler. It requires the recent updates from  FS#9458 , and the scaler output plugging support and greylib output plugin from  FS#9683 . It incorporates my previous pictureflow scaling patch from  FS#9665 , which does not apply cleanly over the other two patches.

The tracklist and album view work exactly as on color targets, in greyscale. The greylib overlay is disabled in the config menu, as this does not rely on color. I have tested on Mini 2G and iPod 4G sims, as well as on iPod video sim (to verify color works correctly).

Reordered loops while creating reflection, so that some math can be moved out of the inner loop. Also made the scaling factor used for the reflection a constant, and of lower precision, to replace a 32x32->64 multiply with a ->32 one.
