When connecting a lowdpi external monitor on hidpi mac, TabChild gets an
UpdateDimensions call, followed by a UIResolutionChanged call. After
the UpdateDimensions call, the content process is in an incorrect state
where it has the dimensions of the new display and scale of the old one.
After the UIResolutionChanged message, the values are again consistent.
In the interim, reflow resizes layers based on the incorrect (old) scale
and subsequently uses those incorrect values when the new scale comes
in. This patch normalizes the message parameters by dividing by scale
(the result is what OS X calls point coordinates) so that this doesn't happen.

This (a) moves ownership of the gfxUserFontSet into FontFaceSet, (b) moves
nearly all of the functionality of nsUserFontSet into FontFaceSet, and (c)
adds a class that inherits from gfxUserFontSet so that we can override some
of its virtual functions and delegate them to the FontFaceSet.
Set the MOZ_DEBUG_RESTYLE environment variable and every restyle will have
detailed logging printed to stderr. By default, restyles for animations are
not logged; you can include them by also setting MOZ_DEBUG_RESTYLE_ANIMATIONS.
If you wish to limit restyle logging to a particular change, you can call
nsPresContext::StartRestyleLogging() and nsPresContext::StopRestyleLogging()
at appropriate points. (You might want to add a couple of helper methods
temporarily on nsIDocument and then expose them to your page with Web IDL
to make them easier to call.) You do not need to have set MOZ_DEBUG_RESTYLE
for this to work.
