A primitive type that encapsulates position information for an atom, with pixel movement included. I.e., it contains a turf (loc) and step_x and step_y offsets. Pixlocs can also be built from absolute world coordinates.
The pixloc of an atom is taken from its loc and step_x/y vars only. If you want the pixloc of its bounds edges or its center, use the bound_pixloc()
proc for that.
Pixlocs support some math operations. A vector can be added or subtracted to a pixloc, and subtracting one pixloc from another will produce a vector. The % and **BROKEN LINK: /operator/modulomodulo** operators are supported, returning a vector.
Other supported procs for pixlocs include:
