Big update with a lot of changes. Should be faster in every situation, many more options, better settings panel, better icons, camera tracking, camera range viewer, separate edge and fill/fluid resolutions. Still a bit more I want to do before I consider it actually complete though.

Add new and higher resolution icons
Add Diagonal Flipped fill method
Add a small amount of surface penetration to line of sight mode
Add a Fluids settings tab
Add many entity drawing options
Add separate resolution options for Edge and Fill
Add camera range settings
Change some settings to be continuous
Change minimap defaults
Change reset to default behaviour to skip some settings (positioning)
Change settings panel to a tabbed layout to avoid the excessively long list of options
Improve settings panel behaviour
Fix fill methods being unimplemented
Fix some tooltips
Fix settings panel formatters
Optimize Horizontal, Vertical, and Diagonal fill methods by drawing one sprite per unbroken line
Optimize terrain data by doing a lot of things differently too much for a single changelog line
Remove Noise fill method
Remove Dot fill method
