Currently the depth/stencil state can only be enabled or disabled. This should be enhanced by exposing the depth and stencil states on a pipeline.

The depth state should expose:

• Bias.
• Compare operation. †
• Test enable/disable. †
• Write enable/disable. †
• Depth boundaries.
• Boundaries test enable/disable. †

The stencil state should expose:

• Test enable/disable. †
• Compare mask.
• Write mask.
• Reference value.

† Part of the static state, i.e. if modified, the pipeline needs to be recreated.
