Disable NPOT support for webgl driver. This also allows to enable mip-mapping again. 

WebGL allows NPOT textures in very specific situations (no mips, no filters, no texture-repeats), but disabling it by default fixes a lot of problems.

// - no mipmapping is used
// - no texture wrapping is used (so all texture_wraps have to be CLAMP_TO_EDGE)
