[Mesa-dev] [PATCH v2 0/5] Implement ARB_sample_locations for nvc0

[Rhys Perry]

This patch set adds support for GL_ARB_sample_locations in mesa core, gallium,
the mesa OpenGL state tracker and the nvc0 driver.

Changes in v2:
- various minor changes/cleanups (mostly formatting and style changes)
- improve error handling
- don't expose the ARB_* variant on ES
- expose NV_sample_locations so the feature is available on ES
- decouple framebuffer and sample location state in the state tracker and nvc0
- rebase to upstream master

Rhys Perry (5):
  mesa: add support for ARB_sample_locations
  gallium: add support for programmable sample locations
  st/mesa: add support for ARB_sample_locations
  nvc0: add support for programmable sample locations
  docs/features: mark GL_ARB_sample_locations as DONE for nvc0
