Test of the bgcolor parameter

I decided to allow any Group object (i.e. any HTML "text block") to have a background color, rather than let some use it but not others. When I adopt the use of inline styles, I may remove this feature, however it is a bit faster to parse a BGCOLOR=blue than it is to parse STYLE="background:blue;" obviously, so perhaps I shall leave it in.

This text should have a cyan background

  1. This text should have a yellow background
