I added support for OpenSWR. OpenSWR is an Intel software renderer that is now part of Mesa. OpenSWR should not be enabled with mesa. To build OpenSWR add the following flags "--llvm --openswr" to the build_visit command line. When you build visit with OpenSWR support it will use the Mesa llvmpipe renderer by default. To enable the OpenSWR renderer you will need to set the GALLIUM_DRIVER environment variable to swr (e.g. "setenv GALLIUM_DRIVER swr"). When VisIt runs with OpenSWR it will print "SWR detected AVX" or "SWR detected AVX2" to the terminal depending on the type of Intel CPU you are running on. git-svn-id: http://visit.ilight.com/svn/visit/trunk/src@30890 18c085ea-50e0-402c-830e-de6fd14e8384
