[Jitblit] Update 7-19-07

[Dan Amelang]

Just when you had given up all hope...Behold, jitblt-enabled pixman:

git://people.freedesktop.org/~dan/pixman

Browse it on the web:

http://gitweb.freedesktop.org/?p=users/dan/pixman;a=tree;h=jitblt;hb=jitblt

Use the configure flag "--enable-jitblt" to enable it.

It's slow and buggy. I have to put it on the back burner for the next
week, but I hope to address some of the most serious issues by the end
of the month.

After I get some sleep, I may do a more thorough write-up of the
problems I'm dealing with at the moment.
