Description

It seems that a lot of applications rely on the OpenGL ES APIs including free software applications.
The application Document Viewer [1][2] needs the OpenGL ES 1.1 API to function properly.

Doing a little research I found that Mesa [1][2] implements both OpenGL ES 1.1 and 2.0 [3]. Mesa is MIT licensed so we should be able to use it.

I'm currently trying to find out if it can be ported to Replicant 4.0, but I'm a bit out of my league here since I've never ported something like this before.

Yes, I know about mesa and I'm already working on using it instead of the (incomplete) Google EGL implementation. That is for Replicant 4.2 though, if it turns out to be doable (it is still currently way too slow for being usable on old devices like the Nexus S).

It turns out that mesa is way too slow to be used on the devices (both with swrast/softpipe and swrast/llvmpipe). We'll still be using the incomplete Android EGL implementation. Any work to improve that is welcome.
