/* This test tests depth clamping / clipping behaviour:
* - When D3DRS_CLIPPING is disabled depth values are *clamped* to the
* minimum/maximum z value.
* - The viewport's MinZ/MaxZ is irrelevant for this.
* - When D3DRS_CLIPPING is enabled depth values are clipped.
* - Pretransformed vertices behave the same as regular vertices.
