/* 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. |
