/* 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.
