MaxIfDepth of 0 means "flatten all the time", not "never flatten".
This is only desirable on hardware that can't support control flow;
software rasterization and most hardware drivers want this.
This alters behavior for swrast as well as i915.

I thought I sent this out, but can't find it in our archives. This
replaces the i915 patch that Eric reviewed by setting this in Mesa core
instead of the i915 driver.
