cairo_move_to(cr, 0.0, 0.0); cairo_line_to(cr, 1.0, 1.0); // draw diagonal "\" cairo_move_to(cr, 0.0, 1.0); cairo_line_to(cr, 1.0, 0.0); // draw diagonal "/"
the "green X" works for me.
Thanks, I get that too.
Though still not sure how to achieve FLTK drawing
coordinates.
So the solution is just leave the scale alone and use 1.0 for
line width.
The default *is* FLTK space, not normalized cairo space, lol.
Yep, found that too.

Happy new year to all !
