OpenGL.GL.EXT.texture_lod_bias

OpenGL extension EXT.texture_lod_bias
This module customises the behaviour of the OpenGL.raw.GL.EXT.texture_lod_bias to provide a more Python-friendly API
Overview (from the spec)
OpenGL computes a texture level-of-detail parameter, called lambda in the GL specification, that determines which mipmap levels and their relative mipmap weights for use in mipmapped texture filtering.
This extension provides a means to bias the lambda computation by a constant (signed) value. This bias can provide a way to blur or pseudo-sharpen OpenGL's standard texture filtering.
This blurring or pseudo-sharpening may be useful for special effects (such as depth-of-field effects) or image processing techniques (where the mipmap levels act as pre-downsampled image versions). On some implementations, increasing the texture lod bias may improve texture filtering performance (at the cost of texture bluriness).
The extension mimics functionality found in Direct3D.
The official definition of this extension is available here: http://www.opengl.org/registry/specs/EXT/texture_lod_bias.txt
