I've completed the tile adjustments and committed them.  Also, I've
committed some adjustments to the tile scaling constants.

Now, when we load a tile, it's a significantly smaller image that
doesn't need much rescaling. This simplifies the drawing calculations
so that we don't lose as much information when we rescale the image
during a paint().

This improves the look of the SVG tiles immensely. I'm really happy
with the results.

With this tile work and the undo/redo work complete, if there are no
objections, I'll do another release in the next day or so.
