- OpenGL ES 2.0 isn't supported, so clean this up - when requesting RETRO_HW_CONTEXT_OPENGL, setting version above 3.0 will crash retroarch - minimum requirement for dolphin is 3.3 (i.e "modern gl") - hw shared context is only required with "gl" video driver (and this option is harmful because it adds some rendering latency)
