Bug #6105 - work around Mozilla firefox 22+
Bug #6105 - work around Mozilla firefox 22+

Mozilla changed the behavior of Canvas 2D context when they added high
DPI support and no longer return mozBackingStorePixelRatio. This causes
gauge.js to fail a rendering test and attempts to use high DPI rendering
mode on normal DPI displays.

I've reported the problem upstream to gauge.js and this work around
turns off HighDPI support for now. It will make the gauge look a little
blurry on retina displays but will fix the rendering problems in firefox
until a proper fix is in place.
