Hi

Wondering:

When a certain mode CAN do hardware 3D, it is not always needed. For
example, if someone only runs normal X, or a 2D game like starcraft, he
doesn't need a Z Buffer, and the Z Buffer space could better be used for
other things.

It seems to me that the accelleration driver should decide that the Z
Buffer must be setup as soon as the first 3D call is made. But in Jons
approach, memory management seems to be done in the Chipset driver. In my
head, a "what belongs where" problem is playing around.

I got setup for Z Buffer and friends in the Accelleration driver, and in
my eyes, this works nice. So I wonder what is the right way to go.

I'm a newbie on the 3D playground, so maybe I'm thinking all wrong...
