Support the maxCanvasPixels option in the thumbnails code

Browse source 
This addresses an inconsistency in the viewer, since the thumbnails don't respect the `maxCanvasPixels` option.
Note that, as far as I know, this has not lead to any bugs since the thumbnails render with a fixed (and small) width, however it really cannot hurt to address this (especially after the introduction of the `maxCanvasDim` option).

To support this a new `OutputScale`-method was added, to avoid having to duplicate code in multiple files.
