The nsBidi API requires the consumer to first call SetPara()
in order to perform bidi resolution and that resets the data
members, so there is no need to recreate nsBidi objects from
scratch each time we need to perform bidi resolution.
Having this API allows us to reuse this object across the
calls to nsBidiPresUtils members.
We want to use a similar model as Chrome on Android does for scaling our display of web content, that is use font inflation for desktop pages and plain text zooming for everything else.
Since we don't want to simply clobber any text zoom that might have been set by the user/front-end code, we allow setting and storing the system font scale separately on the PresContext. We then calculate the effective text zoom value as the product of the system font scale and the current text zoom value.
Any function that is using the PresContext's TextZoom value for layouting/rendering is switched over to this new EffectiveTextZoom value, whereas functions that are interested in the text zoom as actually set by the user/front-end (e.g. the nsDocumentViewer, or the code responsible for copying text and full zoom settings into the new PresContext on page navigation) continue using the plain TextZoom value.
As long as font inflation is enabled in principle (e.g. font.size.inflation.minTwips != 0), every page starts out as eligible for font inflation until the relevant meta viewport tags marking the page as "mobile friendly" have been detected. Since the PresShell caches the font inflation state and only recalculates it when necessary, we make use of that and set the PresContext's system font scale as necessary whenever the font inflation state has been refreshed.

This patch does a few things:
* Buckets invalidations by transaction ID, and sends MozAfterPaints events for them when the associated composite completes.
* Creates a separate EventualDidPaint timer for each transaction ID we have invalidations for rather than just using one.
* Removes NotifyDidPaintForSubtree(PAINT_LAYERS), as it was only necessary for the existing bucketing mechanism.

We added this so that MozAfterPaint events would be delivered to hidden documents as part of bug 539356, but I don't remember what needed it.
It doesn't appear to be necessary for any tests any more, so let's just get rid of it

In non-e10s, all tabs of a window would share one nsRootPresContext. When
switching tabs, the tab switch paint would trigger a call to
nsRootPresContext::ComputePluginGeometryUpdates, which would call
SetEmptyWidgetConfiguration on all registered nsPluginFrames, notably also
those inside the tab that was hidden.
With e10s, every tab has its own nsRootPresContext, and paints in one tab do
not trigger calls to nsRootPresContext::ComputePluginGeometryUpdates on the
root pres contexts of other tabs. So when painting the new tab, the registered
plugin frames in the old tab were not notified that they were now hidden.
This patch now does that in TabChild::MakeHidden.
