Here are patches for the NaCl backend implementation. While testing I
noticed that there is a general issue with Chrome and DRI3 which is well
described here: http://keithp.com/blogs/chromium-dri3/ . So for testing
on DRI3 you'll need to use '--disable-gpu-sandbox' for this to work.

Otherwise you will see :
libGL error: DRI3 Fence object allocation failure Operation not permitted"

which results in everything else failing, like creation of graphics
context and so on. I haven't checked what's the status of fixing this
but it is good to know when testing. This happened to me on Fedora 21.

The whole series is in a branch here:

and a 'demo' of gl_basic available here:

Note, I will be extending this to support OpenGL ES 3.0 later/soon. I'm
also investigating how to make this work for "portable native client",
