-/* Display list compiler attempts to store lists of vertices with the
- * same vertex layout. Additionally it attempts to minimize the need
- * for execute-time fixup of these vertex lists, allowing them to be
- * cached on hardware.
- *
- * There are still some circumstances where this can be thwarted, for
- * example by building a list that consists of one very long primitive
- * (eg Begin(Triangles), 1000 vertices, End), and calling that list
- * from inside a different begin/end object (Begin(Lines), CallList,
- * End).
- *
- * In that case the code will have to replay the list as individual
- * commands through the Exec dispatch table, or fix up the copied
- * vertices at execute-time.
- *
- * The other case where fixup is required is when a vertex attribute
- * is introduced in the middle of a primitive. Eg:
- * Begin(Lines)
- * TexCoord1f() Vertex2f()
- * TexCoord1f() Color3f() Vertex2f()
- * End()
- *
- * If the current value of Color isn't known at compile-time, this
- * primitive will require fixup.
- *
- *
- * The list compiler currently doesn't attempt to compile lists
- * containing EvalCoord or EvalPoint commands. On encountering one of
- * these, compilation falls back to opcodes.
- *
- * This could be improved to fallback only when a mix of EvalCoord and
- * Vertex commands are issued within a single primitive.
