change naming in all the backends vertex managers to make more easy to continue with the merge an some future improvements. please test this as i'm interested in knowing the performance in linux and windows with the different hardware platforms.

// Ikaruga uses (nearly) NO display lists!
|
|
// Zelda WW uses TONS of display lists
|
|
// Zelda TP uses almost 100% display lists except menus (we like this!)
|
|
// Super Mario Galaxy has nearly all geometry and more than half of the state in DLs (great!)
|

// Note that it IS NOT GENERALLY POSSIBLE to precompile display lists! You can compile them as they are
|
|
// while interpreting them, and hope that the vertex format doesn't change, though, if you do it right
|
|
// when they are called. The reason is that the vertex format affects the sizes of the vertices.
