The quadop-based method we currently use on all chipsets already
provides the fine version of the derivatives.

This extension is identical to NV_texture_barrier. Alias
glTextureBarrier to the existing glTextureBarrierNV and use the existing
NV_texture_barrier extension bit.

These two were added ages ago, with an explicit comment "Hacks ..."
They have been insufficient for years and maintainers needed to
explicitly handle the build themselves.
Rather than lying and pretending that it works, just kill this hack and
let maintainers build things the way it should be done for their
distribution.
Document the removal in the release notes.

I don't know of any hardware which supports it.
With this, GL_OES_compressed_ETC1_RGB8_texture is supported if RGBA8
is supported.

Add a new winsys and target that can be used with a dri2 state tracker
and loader instead of drisw. This allows to use gbm as a dri2/image
loader and avoid the extra copy from the backbuffer to the shadow
frontbuffer.
The new driver is called "kms_swrast", and is loaded by gbm as a
fallback, because it is only useful with the gbm platform (as no buffer
sharing is possible)
To force select the driver set the environment variable
GBM_ALWAYS_SOFTWARE

- Rebase on top of gallium megadriver.
- s/text/test/ in configure.ac (Spotted by Andreas Pokorny).
- Add scons support for winsys/sw/kms-dri and fix the build.
- Provide separate DriverAPI, due to different InitScreen hook.

Only supported on evergreen and later. Currently limited
to single component textures as the hardware GATHER4
instruction ignores texture swizzles.
Piglit quick run passes on radeon 6670 with all
applicable textureGather tests, no regressions.

The assumption is that any driver capable of emitting layer from the
vertex shader and supporting viewports should be able to also handle
emitting viewport index from the vertex shader.

If multiple viewports are supported, that implies the presence of a GS
and layered rendering, so we can enable ARB_fragment_layer_viewport as
well.

As far as I can tell, the Intel mesa driver is the only driver in the world
still supporting this legacy extension. If someone wants to do bump
mapping, they can use shaders.

The extension is always supported if GLSL 1.30 is supported.
Softpipe and llvmpipe support is also added (trivial).
Radeon and nouveau support is already done.
