Detailed Description

Stencil attribute group (GL_STENCIL_BUFFER_BIT).

Three sets of stencil data are tracked so that OpenGL 2.0, GL_EXT_stencil_two_side, and GL_ATI_separate_stencil can all be supported simultaneously. In each of the stencil state arrays, element 0 corresponds to GL_FRONT. Element 1 corresponds to the OpenGL 2.0 / GL_ATI_separate_stencil GL_BACK state. Element 2 corresponds to the GL_EXT_stencil_two_side GL_BACK state.

The derived value _BackFace is either 1 or 2 depending on whether or not GL_STENCIL_TEST_TWO_SIDE_EXT is enabled.

The derived value _TestTwoSide is set when the front-face and back-face stencil state are different.
