[Mesa-dev] [PATCH 0/7] Implement AMD_depth_clamp_separate extension

[Sagar Ghuge]

This patch series implements AMD_depth_clamp_separate extension.
Previously I sent patches for comments and based on Ian and Marek's
suggestions, I did some changes. 

1) Get rid of DepthClamp as DepthClampNear + DepthClampFar replaces it
(Marek Olsak & Ian Romanick)

2) Make sure that patch series should build at every commit (Ian
Romanick)

3) Change the sequence of patches (Ian Romanick)

4) Wrote a piglit test, in order to test the extension behavior. It is
also available as a branch on GitLab :
