I was looking at just this issued over the past week or so.  I wanted to ma=
ke the grid lines thicker for the GD terminal.  I found some odd behavior w=
hen using gdImageSetStyle  and gdImageSetThickness  together.

The pixels are not drawn in the order I expected.  I think the style settin=
g will have to set uniquely for each line width.  The style may even have t=
o be adjusted for horizontal and vertical lines.
