Eric Anholt is hired by Broadcom to produce a MIT freesoftware GPU driver stack for the Pi.

Processing 2 using AWT will work without modifications using Eric's new drivers that enable OpenGL ES acceleration inside xorg 1.17+ using mesa3d and the new kernel modesetting vc4 driver.

I am helping Eric to test this new driver using my own "buildroot" cross-compile rpi branch setup

Meanwhile Processing 3.x is under development
Andres Colubri has "switched to GTWindow (no AWT embedding) in the opengl renderer in Processing, I will probably have more questions about NEWT as we move forward with the changes. "
thus Processing 3.x when released _may_ work with the current closed source broadcom drivers.

Its the closed source broadcom drivers that do not support hardware acceleration under X11 that makes OpenGL ES hard on the Pi.
I hope these kind of issues will be sorted when Eric's freesoftware driver is stable.
I expect the first release of Erics work to be included in xorg server 1.17 and mesa3d that gets released around Jan 2015.
