OpenGL extension ARB.texture_non_power_of_two
This module customises the behaviour of the OpenGL.raw.GL.ARB.texture_non_power_of_two to provide a more Python-friendly API
Overview (from the spec)
Conventional OpenGL texturing is limited to images with power-of-two dimensions and an optional 1-texel border. ARB_texture_non_power_of_two extension relaxes the size restrictions for the 1D, 2D, cube map, and 3D texture targets.
There is no additional procedural or enumerant api introduced by this extension except that an implementation which exports the extension string will allow an application to pass in texture dimensions for the 1D, 2D, cube map, and 3D targets that may or may not be a power of two.
An implementation which supports relaxing traditional GL's power-of-two size restrictions across all texture targets will export the extension string: "ARB_texture_non_power_of_two".
When this extension is supported, mipmapping, automatic mipmap generation, and all the conventional wrap modes are supported for non-power-of-two textures
