I am a little hesitant to rely on code that remains a one-off for so
many years. When might these performance improvements from cairo-gles
be fully merged into the main cairo codebase?

Unfortunately, I have almost zero experience with OpenGL on any
platform. But I would like to take advantage of the graphics hardware
if/when possible. Please let me know if you do end up looking into iOS
support. I would love to get some sample/example code to try out.

BTW - how do you enable "QuartzGL"? And, on average, what kind of
performance improvement are you seeing with cairo-gles over the quartz

I would be looking for cairo support at the native level. On Android
you can call into native C/C++ code using JNI from Java. Here is an
example: http://code.google.com/p/android-native-egl-example/
