- * Adaptor/wrappers for GL_DEPTH_STENCIL renderbuffers.
- *
- * The problem with a GL_DEPTH_STENCIL renderbuffer is that sometimes we
- * want to treat it as a stencil buffer, other times we want to treat it
- * as a depth/z buffer and still other times when we want to treat it as
- * a combined Z+stencil buffer!  That implies we need three different sets
- * of Get/Put functions.
- *
- * We solve this by wrapping the Z24_S8 or S8_Z24 renderbuffer with depth and
- * stencil adaptors, each with the right kind of depth/stencil Get/Put functions.
