Title: remove the alias definition for symbolic color names

When using symbolic color names, we can drop the redefinition of the fill and draw colors.

This greatly reduces the file size. A fallback mechanism ensures the definitions are done as usual if either

1. the maximal number of colors are exhausted or
1. symbolic color names are switched off.
