Browse source 
v2: (Nanley Chery)
- Fix condition check.
- Move aux_usage assignment after add_aux_state_tracking_buffer method.

v3: (Nanley Chery)
- Move stencil condition close to depth block.

v4: (Nanley Chery)
- Add DEBUG_NO_RBC condition.

v5: (Nanley Chery)
- Don't add CCS plane explicitly.
- Use isl_surf_supports_ccs.

v6:
- Simplify condition (Nanley Chery)
