Re-think colors.
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.
