OpenGL extension ARB.stencil_texturing
This module customises the behaviour of the OpenGL.raw.GL.ARB.stencil_texturing to provide a more Python-friendly API
Overview (from the spec)
This extension allows texturing of the stencil component of a packed depth stencil texture. Stencil values are returned as unsigned integers. It is not possible to sample both depth and stencil values from the same texture, and this extension allows the app to select which is sampled for the bound texture.
The official definition of this extension is available here:
