| /* 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. |
