Ensure that all public functions in PZC are always called from
the UI thread, so that internal variables are not mutated on
different threads. I also made animatedZoomTo private so that
it can't be inadvertently called from a non-UI thread outside
the class.
Since the geometryChanged function does nothing if the parameter passed
in is false, better to rename the function to be more indicative of
what it actually does, and remove all the resulting dead code.
This removes the hard-coded limit of 1024x2048 tile sizes, and allows for
arbitrary tile-sizes. It will still only allocate texture sizes in powers of
two, however. It replaces the tile size with a buffered-area size, which can be
re-allocated as the screen dimensions change.

Some cleanup: ensure we abort and re-bounce the viewport
if the device is rotated during a double-tap zoom. Also
rename variables to be more appropriate
Send an event to scroll to the focused input field when the
soft keyboard comes up. Ensure that this happens *after* the
viewport change event is sent to Gecko, so that Gecko actually
knows that browser viewport is smaller and doesn't just no-op
the scroll request.
If the Java code is in the middle of a fling when Gecko sends
a viewport update, abort the fling, cancel the velocity, and
re-fling. The re-fling is purely to get the page snapped to an
edge if needed.
Set the render mode to RENDERMODE_WHEN_DIRTY and request a redraw when a layer
transaction ends and when the viewport in LayerController changes. This stops
us from drawing continuously.
Earlier patches mistakenly removed the redraw hint. This restores it, and
alters its behaviour to work correctly with regards to the viewport. This
should help mitigate some checker-boarding and performance issues when panning
and zooming.
This patch reinstates pinch-zooming and adds CSS re-scaling so that after
zooming, the page is rendered at the scaled resolution and you get clear text.
This patch refactors the code to make some of the value names and ownership
clearer, and to add the idea of a 'viewport' within a 'displayport'. The
displayport is the area of the page which is visible to the underlying buffer
and the viewport is the area of the page which is visible through the
application window.
