5. In tnl's struct vertex_buffer, the field "ProjectedClipCoords"
has been replaced by "NdcPtr" to better match the OpenGL spec's
terminology.
6. Since GL_EXT_stencil_two_side has been implemented, many of the
ctx->Stencil fields are now 2-element arrays. For example,
"GLenum Ref" is now "GLenum Ref[2]" The [0] elements are the front-face
values and the [1] elements are the back-face values.
ctx->Stencil.ActiveFace is 0 or 1 to indicate the current face for
the glStencilOp/Func/Mask() functions.
ctx->Stencil.TestTwoSide controls whether or not 1 or 2-sided stenciling
is enabled.
