Is this really necessary, and if so why? It's the first instance in this file
which would use a regexp to match all driver vendors.

It is to avoid a nasty bug. I should find a proper way. The explanation is that
all gpu driver bug workarounds that are applied in browser process will always
be applied in the gpu process. Whereas after updating gl_renderer for example,
some workarounds might disappear since they can hit an exception from
kGpuDriverBugListJson. 
Without this change this CL it will not pass the Linux Intel builder since this
builder has 'Core Profile' in its gl version so it will hit that exception
bellow and fails as explained above.
I need to think about it.
