[Mesa-dev] [PATCH 0/4] Multiple viewports in Gallium

[Zack Rusin]

This series adds support for multiple viewports/scissors
to gallium and implements it in llvmpipe. All the other
drivers still support just a single viewport/scissor
combo and their behavior should be exactly the same as
it was.

Zack Rusin (4):
  gallium: Add support for multiple viewports
  draw: implement support for multiple viewports
  util/blitter: make sure the blitter can restore all viewports
  llvmpipe: implement support for multiple viewports
