[Mesa-dev] [PATCH] draw: use the prim count for ia primitives

[Jose Fonseca]

----- Original Message -----
> Number of vertices to fetch doesn't always equal the number of input
> vertices. To correctly compute the number if IA primitives we need
> to use the total number of input vertices, not only those that
> need to be fetched.
