* OK, so here are the changes to rendering as far as I know:
|
|
* Vertex formats specify how the methods are arranged
|

* Color has to be called for every vertex, I think.
|
|
* The new methods thing is a bit weird, because other than the number of arguments there is
|
|
* essentially no difference between pos, tex, color, normal and lightmap. At least they make
|
|
* the code more readable.
