## Detailed Description

Wraps the OpenGL function glTexEnv(), see also http://www.opengl.org/sdk/docs/man/xhtml/glTexEnv.xml for more information.

Note:
  A TexParameter defines a set of variables associated to a Texture while TexGen and TexEnv define a set of variables associated to a TextureUnit.
