+ *
+ * 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
