This avoids some inefficiency in creating a temporary Picture for every glyph at rendering time. My measurements with an i965 showed the previous patch causing a 10-15% slowdown for NoAccel and XAA cases, (while providing an 18% speedup for EXA). With this change, the NoAccel and XAA performance regression is eliminated, and the overall EXA speedup, (before any of the glyphs-as-pixmaps work), is now 32%.
