Found this little quirk; the following JSFX:
Code:
@gfx
gfx_set(1,1,1);
gfx_line(0,0,100,100,0);
gfx_line(10,0,110,100,1);
...generates these results (on Linux and Windows):
...there is a kink in the non-aliased line, and subtle shading anomaly in the aliased line. Maybe a fencepost error in there, eh?
