GLES2 drivers don't advertise the GL_OES_texture_npot extension

[Alexandros Frantzis]

The GLES2 extension string doesn't contain "GL_OES_texture_npot", although it does contain "GL_IMG_texture_npot". GL_OES_texture_npot is required by the Cairo GLES2 backend.

I am not sure if the two extensions are equivalent, as I am not able to find any information on GL_IMG_texture_npot.

From SGX documentation:

Supported:
IMG_texture_npot - Allows mipmap filters to be used with non-power-of-two textures.

Not going to be supported at SGX540:
OES_texture_npot - Allows non-power of two textures to be mipmapped and wrapped with non-clamp modes.

Cogl (http://git.gnome.org/browse/cogl/) uses the IMG extension, probably just using the mipmap filters.

Closing as Won't Fix because the documentation says that this will not be supported.
