Ticket #14076: mesa-17.1.10.recipe

SUMMARY="Multi-platform GL implementation"
DESCRIPTION="Mesa is an open-source implementation of the OpenGL \
specification. The OpenGL specification documents a system for rendering \
interactive 3D graphics. Mesa fills the role of the Haiku OpenGL kit \
providing 3D rendering to Haiku applications."

SUMMARY_swpipe="The Mesa LLVM enhanced Gallium software pipe renderer"
DESCRIPTION_swpipe="This 3D BGLRenderer add-on provides Gallium LLVM \
enhanced software rendering. Software pipe rendering performs all \
3D rendering on the systems CPU and doesn't require any specialized \
hardware. The usage of LLVM over traditional rasterization gives this \
renderer a boost in performance.

Gallium software pipe rendering is in an extremely early state as of \
this version of Mesa, and may not function as expected."
