SetRenderTargets on OpenGL ES devices

[jnoyola]

I don’t think it’s officially supported on iOS yet, but I added GLES 3 support in this thread and got Multiple Render Targets working on iOS with an HLSL shader. I thought it was supposed to work on Android already, but I haven’t tried.

[Solved] iOS GLES 3.0

Brilliant! That was the missing piece. Here is the commit that I made to upgrade iOS to GLES 3.0 on a clean develop branch. I don’t know if all my changes were necessary, or if there are some important ones that I missed, but I now have MRT working. Thank you so much! It would certainly need to be cleaned up a bit if anyone wanted to support automatically falling back to 2.0, but I’m not sure if that’s a common case given that people usually use 3.0 for its exclusive features.
