It was mentioned that selectable Antialiasing would be nice... This is
what LW does when you select Adaptive Sampling and enter a threshold level:
The higher your threshold, the less LW will antialias, concentrating on
higher contrast edges.
The Threshold level is the amount in RGB values that the green component
of the two neighboring pixels has to be seperated by before it will be
antialiased.
If the greens are in range, then the other values are tested to fall into
ranges and if not, the pixels will be antialiased.
