 *     when D3DRS_CLIPPING is enabled. Pretransformed vertices behave the
 *     same as regular vertices here.
 *   - With hardware vertex processing, D3DRS_CLIPPING seems to be ignored.
 *     Normal vertices are always clipped. Pretransformed vertices are
 *     clipped when D3DPMISCCAPS_CLIPTLVERTS is set, clamped when it isn't.
 *   - The viewport's MinZ/MaxZ is irrelevant for this.
