Tip:#webgl and radeon gallium3d : use chromium

I have tried to force both mozilla and google-chrome to render webgl pages from learnwebgl
but there were only errors , so i had a surprise when i opened chromium browser (you know the one with the blue icon) by mistake
that webgl worked out of the box on my system with quite good fps and usable

Also quake3 webgl demo is quite watchable at ~50-60 fps
