Ok, this is a simple problem...but I can't seem to find an answer. I
am trying to draw a single pixel horizontal line. Sometimes, depending
on where it is drawn on the screen, it is a crisp single pixel line
other times it is very fuzzy.
Any ideas? How do I guarantee that the line will always draw crisp?
Draw it from the centers of the pixels. A line from (10.0, 10.0) to
(20.0, 10.0) lands exactly between the pixels. A line from (10.0, 10.5)
to (20.0, 10.5) runs through the center of the pixels.
