- '''OpenGL extension SGIS.detail_texture
-
- Overview (from the spec)
-
- This extension introduces texture magnification filters that blend
- between the level 0 image and a separately defined "detail" image.
- The detail image represents the characteristics of the high frequency
- subband image above the band-limited level 0 image. The detail image is
- typically a rectangular portion of the subband image which is modified
- so that it can be repeated without discontinuities along its edges.
- Detail blending can be enabled for all color channels, for the alpha
- channel only, or for the red, green, and blue channels only. It is
- available only for 2D textures.
-
- WARNING - Silicon Graphics has filed for patent protection for some
- of the techniques described in this extension document.
-
- The official definition of this extension is available here:
- http://oss.sgi.com/projects/ogl-sample/registry/SGIS/detail_texture.txt
