  Message : Clean up workarounds/features to single location. Rename all workarounds structs to features, and move the lists to a shared location in include/platform (to help with documentation, see: https://cs.chromium.org/chromium/src/ui/gl/gl_switches.cc?sq=package:chromium&g=0&l=69) Bug: angleproject:1621 Change-Id: I4069f08131db5e886047a007efb5d7764dfee5f2 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/1660952 Commit-Queue: Jonah Ryan-Davis <jonahr@google.com> Reviewed-by: Jamie Madill <jmadill@chromium.org>
