Removed many bogus 'lakes' which were actually mischaracterized permanent snow.
Added styling for scree, talus, and meadow/marshes.
Changed font for SPS peaks to slightly larger, darker, and italic to set them apart from non-SPS peaks.
Not a tile change, but I added UTM coordinate display in lower right.
Here's an image showing most of these new features:
Note that I screwed up the land cover in Yosemite National Park by accidentally styling it with two sets of
landcover data. Obvious side effects of this are that the whole area is generally too green and the permanent
snow sections look funny. It will take me a few days to fix this.
