Deprecated: I am not using this anymore, therefor it might only serve as a reference to re-implement something similar for current versions of piston.
An OpenGL ES 2D back-end for the Piston game engine
Maintainers: @drakulix Regulary updated fork of PistonDevelopers/opengl_graphics
OpenGL ES needs to load function pointers before use. If you are experiencing strange error messages like "X not loaded" this is likely the case. To do this, see the README in gl-rs
The necessary GL interface is exposed under opengles_graphics::gl.
Currently only supportes GLSL Version 100 & GL ES Version 2.0.
