The motivation behind this is to add some self-documentation in the code
about how each CAP can be used.
The idea is:
- enum pipe_cap is only valid in get_param
- enum pipe_capf is only valid in get_paramf
Which CAPs are floating-point have been determined based on how everybody
except svga implemented the functions. svga have been modified to match all
the other drivers.
Besides that, the floating-point CAPs are now prefixed with PIPE_CAPF_.
It's intended to indicate whether the driver/hardware supports reading
of the values written into shader outputs.

This is required for an accurate implementation of d3d1x's
CheckFormatSupport query.
It also seems generally useful for state trackers, which could
choose alternative rendering paths or formats if blending would
come at a significant performance loss.
Adds a possibility for the state tracker manager to query the
target for a specific configuration.

v2: fixup formatting of table + tabs
Signed-off-by: Dave Airlie <airlied@redhat.com>
This add support for unsigned/signed integer types via adding a 'pure' bit
in the format description table. It adds 4 new u_format get/put hooks,
for get/put uint and get/put sint so that accessors can get native access
to the integer bits. This is used to avoid precision loss via float converting
paths.
It doesn't add any float fetchers for these types at the moment, GL doesn't
require float fetching from these types and I expect we'll introduce a lot
of hidden bugs if we start allowing such conversions without an API mandating
it.
It adds all formats from EXT_texture_integer and EXT_texture_rg.
0 regressions on llvmpipe here with this.
(there is some more follow on code in my gallium-int-work branch, bringing
softpipe and mesa to a pretty integer clean state)

We were checking whether render_condition is set. That was not reliable,
because it's always set with trace and noop regardless of driver support.

All drivers support it (well, except Cell). The boolean option is going away
from core Mesa too.

Since Mesa is now capable of supporting up to 8 clipping planes

This moves the gallium interface for clears from using a pointer to 4 floats to a pointer to a union of float/unsigned/int values.
Notes:
1. the value is opaque.
2. only when the value is used should it be interpretered according to
the surface format it is going to be used with.
3. float clears on integer buffers and vice-versa are undefined.
v2: fixed up vega and graw, dropped hunks that shouldn't have been in

Resolve via glBlitFramebuffer allows resolving a sub-region of a
renderbuffer to a different location in any mipmap level of some
other texture, and, with a new extension, even scaling. Therefore,
location and size parameters are needed.
The mask parameter was added because resolving only depth or only
stencil of a combined buffer is possible as well.
Full information about the blit operation allows the drivers to
take the most efficient path they possibly can.
