Hi,
this patch series implements ARB_depth_buffer_float in Mesa and Gallium. There
is complete r600g/r600-r700 support in my private branch, which passes the same
tests that pass for Z24S8. Softpipe has only sampler support. This has turned
out to be not so trivial, so it's possible I missed something.
I did not implement NV_depth_buffer_float, because it's not compatible with the
ARB variant. (GL_DEPTH_COMPONENT32F != GL_DEPTH_COMPONENT32F_NV etc.) The NV
extension can operate on unclamped depth values, whereas the ARB one always
clamps them.
Please review.
