/* KW: If are compiling, we don't know whether eval will produce a
* vertex when it is run in the future. If this is pure immediate
* mode, eval is a noop if neither vertex map is enabled.
*
* Thus we need to have a check in the display list code or
* elsewhere for eval(1,2) vertices in the case where
* map(1,2)_vertex is disabled, and to purge those vertices from
* the vb. This is currently done
* via modifications to the cull_vb and render_vb operations, and
* by using the existing cullmask mechanism for all other operations.
*/


/* KW: Because the eval values don't become 'current', fixup will flow
* through these vertices, and then evaluation will write on top
* of the fixup results.
*
* This is a little inefficient, but at least it is correct. This
* could be short-circuited in the case where all vertices are
* eval-vertices, or more generally by a cullmask in fixup.
*
* Note: using Obj to hold eval coord data. This data is actually
* transformed if eval is disabled. But disabling eval & sending
* eval coords is stupid, right?
