PDL and SDL

Hey folks -

I'm working on creating a simulation/animation for my research.  I mostly
use PDL for my computational stuff.  I was reading through your docs and it
occurred to me that it would be really handy if there was some way to
convert between a Rectangle and a piddle.  I assume that a rectangle object
is stored in memory as an array packed into a scalar, or something like
that.  PDL has powerful element selection capabilities and can make writing
hand-rolled C code a cinch.  Perhaps we could work together to create a
couple of functions that look like:

my ($red_piddle, $green_piddle, $blue_piddle, $alpha_piddle) =
sdl_rect_to_pdl($rectangle);
# do something with the values in the different channels.
$rectangle = pdl_to_rect($red_piddle, $green_piddle, $blue_piddle,
$alpha_piddle);

This could be very powerful.  What do you think?

Thanks!
David
