Different coloured backgrounds

Hi there, and thanks for this awesome work.

Not sure if I should file this one under support of feature request, but what I want to do is to run all filters on the block titles. The reason is that I want different background images based on the block titles class name, and from what I have read it's not possible in any other way.

So I guess my question is, how do I loop through and run all the filters on $block->subject for example?

In worst case I could always put down the profile names in an array and do it that way, but I would be nicer if I could just grab them automatically.

Perhaps there is some other way to do this?

Thanks,
