[Rails-devel] SVG Tile cleanups

[brett l. <wak...@gm...>]

I've committed the first batch of cleanups for the SVG tiles.

The last time I touched these files, it looks like there was some
slight variation in the hex size and positioning within the image
canvas. This was causing some unpredictable positioning when these
images were laid out on the map as well as some strange skewing when
applying an affine transform.

So, I'm going back and adjusting all of the tiles to better fit within
the canvas dimensions.

I'm fairly happy with the results. The 1830 map looks significantly
more uniform.

The other thing I'm working on, but haven't committed yet is a
solution for the horrible dithering on the map. In large part, this is
due to AffineTransform's scale() method. We use HexIcons for the tile
lay preview, which does an excellent smooth rescaling. I'd love to use
HexIcons for the map, but there's no way to rotate a HexIcon. So, I'm
exploring a few different ways of removing the need to use
AffineTransform's scale() method.
