Hi,

What is the easiest method for obtaining the pixel coordinates of a
particular point in some Data object's domain space? In the past, I
have used MouseBehavior.findRay to go the other way (the "hard" way):
convert from pixel coordinates to cursor coordinates, and from there
to domain coordinates using ScalarMap ranges. But what about going
from domain to pixel? I am mostly interested in doing so for 2D
displays.

Thanks,
Curtis
