 This feature is implemented in the :ref:`Draw` module but may also be

+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.
