Fix for order of Map name saving, painting perf

Performance changes done for PaintFog, PaintNewFog, and PaintMap. Draw
time of 10000x10000 image remains at 120ms for scroll, 180ms for newfog,
which is weird to me considering the changes... Will keep trying.
Ditched NewFog's Bitmap

Replaced with a runtime drawing of the Point values themselves. Much
smoother polygon now.
