COLORITEM & kin

[Attila Csipa]

Is there interest (as in would you support) development of a COLORITEM (and 
related BACKGROUNDCOLOR, etc items) functionality ? This would work as 
LABELITEM and similar attribute related tags. The rationale behind this is 
that I have maps with too many colours to squeeze them into separate classes, 
and worse yet, these should (dis)appear dynamically. Or perhaps there is 
another way of doing this ? I have looked into STYLEITEM and some fancy 
includes, but they are still not good enough due to the number and dynamic of 
colours used.
