@ -340,3 +340,26 @@ clip_plane_enable
If any clip distance output is written, those half-spaces for which no
clip distance is written count as disabled; i.e. user clip planes and
shader clip distances cannot be mixed, and clip distances take precedence.
conservative_raster_mode
The conservative rasterization mode. For PIPE_CONSERVATIVE_RASTER_OFF,
conservative rasterization is disabled. For IPE_CONSERVATIVE_RASTER_POST_SNAP
or PIPE_CONSERVATIVE_RASTER_PRE_SNAP, conservative rasterization is nabled.
When conservative rasterization is enabled, the polygon smooth, line mooth,
point smooth and line stipple settings are ignored.
With the post-snap mode, unlike the pre-snap mode, fragments are never
generated for degenerate primitives. Degenerate primitives, when rasterized,
are considered back-facing and the vertex attributes and depth are that of
the provoking vertex.
If the post-snap mode is used with an unsupported primitive, the pre-snap
mode is used, if supported. Behavior is similar for the pre-snap mode.
If the pre-snap mode is used, fragments are generated with respect to the primitive
before vertex snapping.
conservative_raster_dilate
The amount of dilation during conservative rasterization.
subpixel_precision_x
A bias added to the horizontal subpixel precision during conservative rasterization.
subpixel_precision_y
A bias added to the vertical subpixel precision during conservative rasterization.
