'''OpenGL extension APPLE.texture_2D_limited_npot
This module customises the behaviour of the
OpenGL.raw.GLES1.APPLE.texture_2D_limited_npot to provide a more
Python-friendly API
Overview (from the spec)
Conventional OpenGL ES 1.X texturing is limited to images with
power-of-two (POT) dimensions. APPLE_texture_2D_limited_npot extension
relaxes these size restrictions for 2D textures. The restrictions remain
in place for cube map and 3D textures, if supported.
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 2D texture dimensions that may or may
not be a power of two.
In the absence of OES_texture_npot, which lifts these restrictions, neither
mipmapping nor wrap modes other than CLAMP_TO_EDGE are supported in
conjunction with NPOT 2D textures. A NPOT 2D texture with a wrap mode that
is not CLAMP_TO_EDGE or a minfilter that is not NEAREST or LINEAR is
considered incomplete. If such a texture is bound to a texture unit, it is
as if texture mapping were disabled for that texture unit.
The official definition of this extension is available here:
