This removes the logging, locking and allocations from getViewTransform.
This reduces the time spent from an median of 6.3ms to 0.061ms
We use a new scheme where the view transform is immutable and the member
variable containing it is atomically overwritten. So we may get a slightly old
view transform but this won't be a problem.
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.

Check more values in browser.js when updating the viewport, and restructure
the JSON conversion in Java so that it's easier to tell what value caused a
bad viewport if it comes from Java.
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.
