[Mesa-dev] [PATCH 0/5] Implement clip control v3

[Mathias.Froehlich at gmx.net]

From: Mathias Fröhlich <Mathias.Froehlich at gmx.net>

Hi,

The next approach to bring decent depth buffer precision to mesa.

The patch series implements ARB_clip_control in mesa and enables the
extension for the gallium drivers.

v2:
Only enable on those gallium drivers that already support clip_halfz.

v3:
Add more comments.
Restrict getting clip control state to the availability
of ARB_clip_control.
Move to transformation state.
Handle clip control state with the GL_TRANSFORM_BIT.
Move _FrontBit update into state.c.
Handle clip control state with MESA_META_TRANSFORM.
Initially enable on ilo.
Use extension enable infrastructure to connect PIPE_CAP_CLIP_HALFZ
with ARB_clip_control.

Please review.

Greetings
Mathias
