-Actually there is some progress. The miGlyphs() function uses a scratch pixmap to render characters into which it then renders into the target pixmap. Since off-screen pixmaps in XAA are currently broken and the Xorg people refuse to fix it the scratch pixmap will be in RAM with all XAA drivers resulting in software rendering. I got around that by implementing a private Glyphs() method for the [[crime]] driver which gives a nice speedup but still gets us nowhere near the performance we had with Xorg 1.4. A private Glyphs() implementation for XAA which avoids the scratch pixmap resulted in a small but measurable speedup with the sunffb driver. +Actually there is some progress.

I have the docs and the hardware, only need some spare time
