There's no XForms function to do this and, in fact, there's really no
X function to do this directly as far as I can tell.
This is kind of a hack but you can use one of the appropriate
fl_get_*_mouse() functions and then, having the location of the
cursor, get a 1x1 subimage containing the pixel with XGetSubImage(),
use XGetPixel() to get the actual pixel value, and then, if you're in
a PseudoColor Visual, do the inverse translation from LUT index to
actual RGB triplet.
My head hurts just thinking about it.
