D3D9 has a different behaviour for depth bias.
For OGL/D3D1X, the depth bias unit is the
minimal resolvable value for the depth buffer,
which depends on the format (and has different
behaviour for float depth buffers).
For D3D9, the depth bias unit is 1.0f.

Some hardware supports primitive restart on patch primitives, and other
hardware does not. Modern GL and ES include a query for this feature;
adding a capability bit will allow us to answer it.
As far as I know, AMD hardware does not support this feature, while
NVIDIA and Intel hardware does. However, most Gallium drivers do not
appear to support tessellation shaders yet. So, I've enabled it for
nvc0 and disabled it everywhere else.

Add PIPE_CAP to determine if the GL extension
'GL_ARB_framebuffer_no_attachments' shall be
supported.
The driver is required to support 'PIPE_FORMAT_NONE'
via its 'is_format_supported()' callback in order
to determine the MSAA modes the hardware supports so
that values requested from the application using
'GL_ARB_framebuffer_no_attachments' may be quantized
to what the hardware expects.
V.2:
Fix doc for a more detailed description of the PIPE_CAP
and the corresponding GL constant.
V.3:
Renamed and repurposed once again.
V.4:
Remove CAP from cap_mapping array.

This patch adds a new interface to support hardware mipmap generation.
PIPE_CAP_GENERATE_MIPMAP is added to allow a driver to specify
if this new interface is supported; if not supported, the state tracker will
fallback to mipmap generation by rendering/texturing.
v2: add PIPE_CAP_GENERATE_MIPMAP to the disabled section for all drivers

This avoids a serious r600g bug leading to a GPU hang.
The chances this bug will get fixed are pretty low now.
I deeply regret listening to others and not pushing this patch, leaving
other users with a GPU-crashing driver. Yes, it should be fixed
in the compiler and it's ugly, but users couldn't care less about that.

Plus a new PIPE_CAP_VERTEXID_NOBASE query. The idea is that drivers not
supporting vertex ids with base vertex offset applied (so, only support
d3d10-style vertex ids) will get such a d3d10-style vertex id instead -
with the caveat they'll also need to handle the basevertex system value
too (this follows what core mesa already does).
Additionally, this is also useful for other state trackers (for instance
llvmpipe / draw right now implement the d3d10 behavior on purpose, but
with different semantics it can just do both).
Doesn't do anything yet.
And fix up the docs wrt similar values.
v2: incorporate feedback from Brian and others, better names, better docs.
