glGenerateMipmap is an OpenGL 3.0 API, needs replacing
glGenerateMipmap
was added with OpenGL 3.0, which means users whose driver only supports OpenGL 2.1 will not be able to run the program if mipmaps are enabled. A software implementation is needed to replace this API call.
This API is part of OpenGL ES 2.0 so it may be possible to rely on ANGLE to handle this instead.
