* Re-think colors.Tavian Barnes2011-12-1428-887/+716
| | | | | | | | | Color is a property of light, and thus doesn't include information about transparency. But canvas pixels and object pigments represent a color and a degree of transparency. The new type dmnsn_tcolor/ TColor encapsulates that information. Also, fix the transparent shadow implementation.
