@@ -74,6 +74,26 @@ The integer capabilities:
property FS_COORD_PIXEL_CENTER with value HALF_INTEGER is supported.
* ``PIPE_CAP_TGSI_FS_COORD_PIXEL_CENTER_INTEGER``: Whether the TGSI
property FS_COORD_PIXEL_CENTER with value INTEGER is supported.
* ``PIPE_CAP_DEPTH_CLIP_DISABLE``: Whether the driver is capable of disabling
depth clipping (through pipe_rasterizer_state)
* ``PIPE_CAP_SHADER_STENCIL_EXPORT``: Whether a stencil reference value can be
written from a fragment shader.
* ``PIPE_CAP_TGSI_INSTANCEID``: Whether TGSI_SEMANTIC_INSTANCEID is supported
in the vertex shader.
* ``PIPE_CAP_VERTEX_ELEMENT_INSTANCE_DIVISOR``: Whether the driver supports
per-instance vertex attribs.
* ``PIPE_CAP_FRAGMENT_COLOR_CLAMPED``: Whether fragment color clamping is
supported.
* ``PIPE_CAP_MIXED_COLORBUFFER_FORMATS``: Whether mixed colorbuffer formats are
supported, e.g. RGBA8 and RGBA32F as the first and second colorbuffer, resp.
* ``PIPE_CAP_VERTEX_COLOR_UNCLAMPED``: Whether the driver is capable of
outputting unclamped vertex colors from a vertex shader. If unsupported,
the vertex colors are always clamped. This is the default for DX9 hardware.
* ``PIPE_CAP_VERTEX_COLOR_CLAMPED``: Whether the driver is capable of
clamping vertex colors when they come out of a vertex shader. If unsupported,
the vertex colors are never clamped. This is the default for DX10 hardware.
If both clamped and unclamped CAPs are supported, the clamping can be
controlled through pipe_rasterizer_state.
