PDFCroppingBox

Hello all,

I have a question about PDFCroppingBox. Here's the background.

I've modified an existing style file for my use. I would like
to use the same basic style with various colour schemes. In order
to avoid defining multiple style files (one for each scheme), I've 
made the colour scheme an optional argument to my style file.

So, instead of

    \documentclass[pdf,mystyle]{prosper}

I use

    \documentclass[pdf]{prosper}
    \usepackage[optional colour scheme]{PPRmystyle}

The problem with this second usage is that PPRdefault.sty is first
loaded, and this sets a PDFCroppingBox. Even though PPRmystyle 
has a different definition of PDFCroppingBox, my definition is
ignored, and the one in PPRdefault is retained.

How exactly does PDFCroppingBox work? Is there someway to ensure
that my settings for PDFCroppingBox are used? Or, even better, is
there an alternative way to achieve my original goal?

Thanks for any help.
Mandar.
