Create a Picture as well as a Pixmap at the time of AllocateGlyph

Browse Source 
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%.
