The GPU info api previously told us a driver package name and a driver vendor name, but now we have introduced detection for the gpu architecture too and started to track architecture feature flags that can tell us whether a gpu is a deferred or immediate mode renderer for example or if a software rasterizer is being used. This also adds support for checking more vendor names. We should now detect the following cases: Vendors: Intel, Imagination Technologies, ARM, Qualcomm, Nvidia, ATI Architectures: Sandybridge, SGX, Mali Architecture flags: - vertex tiled - vertex immediate mode - vertex software - fragment deferred - fragment immediate mode - fragment software Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit b3803a0a7c9e663ed219e83626841895c7d95ad7)
