Patch to add support for OpenGL ES 3 on iOS

Currently the UIKit/EAGL backend for SDL's OpenGL context creation API doesn't support OpenGL ES 3, despite iOS 7+ being capable (on devices with the necessary hardware.)

I have attached a patch to add support. It's also slightly more future-proof, so eventual OpenGL ES 4+ capability on iOS should hopefully work without requiring changes to SDL's UIKit/EAGL backend.
Comment 1 Gabriel Jacobo 2014-02-20 14:04:06 UTC 
Looks good to me. As a suggestion, it may be better to move the initialization entirely to the switch statement and error out in the "default" case (in which case the "case 3" should be entirely guarded by #ifdef __IPHONE_7_0)
Comment 2 Sam Lantinga 2014-02-22 23:23:49 UTC 
Fixed, thanks!
