30 * Keith Whitwell <keith@tungstengraphics.com>
36 * The display list compiler attempts to store lists of vertices with the
37 * same vertex layout. Additionally it attempts to minimize the need
38 * for execute-time fixup of these vertex lists, allowing them to be
41 * There are still some circumstances where this can be thwarted, for
42 * example by building a list that consists of one very long primitive
43 * (eg Begin(Triangles), 1000 vertices, End), and calling that list
44 * from inside a different begin/end object (Begin(Lines), CallList,
47 * In that case the code will have to replay the list as individual
48 * commands through the Exec dispatch table, or fix up the copied
49 * vertices at execute-time.
51 * The other case where fixup is required is when a vertex attribute
52 * is introduced in the middle of a primitive. Eg:
54 * TexCoord1f() Vertex2f()
55 * TexCoord1f() Color3f() Vertex2f()
58 * If the current value of Color isn't known at compile-time, this
59 * primitive will require fixup.
62 * The list compiler currently doesn't attempt to compile lists
63 * containing EvalCoord or EvalPoint commands. On encountering one of
64 * these, compilation falls back to opcodes.
66 * This could be improved to fallback only when a mix of EvalCoord and
67 * Vertex commands are issued within a single primitive.

83 * NOTE: Old 'parity' issue is gone, but copying can still be
84 * wrong-footed on replay.
