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
