Didn't you rename g_browser?

[nduca, 2010/12/07 01:03:40]

I did for gpu_internals, but gpu_internals browserBridge !=  NetInternals
g_browser. If there's desire is to change it there as well, I can, but I'd
suggest a separate CL since its netinternals only. This conditional keeps NI
working without that more sweeping change.
