> gpu: Allow overriding GPU driver workarounds via command line
> 
> This change allows you to enable GPU driver workarounds by providing command
> line switches with the name of the workaround. These workarounds are used
> instead of the workarounds loaded from the JSON data. The command line switch
> will be propagated into the GPU process allowing these to be applied both with
> in-process GPU and without.
> 
> BUG=347130
> TEST=run content_gl_test or chromium with and without switches and observe
> workarounds being applied.
