 * figure out why anti-aliased font rendering with [[XAA]] in [[Xorg]] 1.6 is ridiculously slow compared to 1.4<br>  * figure out why anti-aliased font rendering with [[XAA]] in [[Xorg]] 1.6 is ridiculously slow compared to 1.4<br>
 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 ( not that XAA knows how to accelerate vram-to-vram composite ops anyway ). 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.
