As of ab83c862, the canvas scaling setting is now used on OSX
(before it was ignored). Legacy settings would have this set to 1.0,
which would not automatically scale the canvas and break on Retina
displays. OSX auto detection works well enough in wx 3.0, so we
can use it now.
You can now choose the behavior of dragging with the
middle and right mouse buttons.
You can also choose which modifier keys to use for
panning and zooming with the scroll wheel or trackpad.
You can also customize the zoom speed, which makes
it possible to have a good zoom experience on a wider
range of input devices.
You can also now zoom by dragging with the right or
middle button if desired.
