Suppress manual task processing to prevent skewing of benchmark figures

Manually processing the redraw tasks vastly affects the current benchmark
results, dwarfing impacts from most other subsystems. Disabling this for
now to aid tuning of non-UI components.

Re-align downgrade whitespace logic to match upgrade whitespace

Downgrade whitespace now follows the same logic as upgrade, and will
downgrade a whitespace element just to the left of the step, and to the
left of the next step to the right.

Using step iterators instead of position iterators also fixes some failing
operation tests by ensuring one step to the right is checked irrespective
of how many positions there are between steps.

Make canvas overflow hidden.

Even though the sizer is scaled, it's original 'ghost'
size is used to hint scrollbars in Firefox (unlike in Chrome).
Therefore the canvas's overflow needs to be hidden to
prevent this ghost size leak.
Re-apply inline-block to canvas element on resizing.
Chrome tends to forget this property after a relayout.
Do not show a scrollbar in slideshows in the viewer.
Slideshows are (currently) meant to be navigated by
the nav buttons.
Let sizer overflow out of the canvas during
a pinch-zoom gesture.
Center all slideshow pages
Move slideshow CSS customizations for canvasContainer to viewer.css
