-/* 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.

+/* 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.
