Hello Erik,
The Xlib version (both with X11 drawing and cairo) currently segfaults
in xtfuncs.c:overdrawpixmap at the first call to XtGetValues. The
segfault happens when I change color.
If I start with a line and change to color to say green, there is no
problem, since its index> NUMBER_OF_COLORS. But if I select black, the
index is 1. And the addtocolorlist has never been called for this
index. The proper index I think should have been NUMBER_OF_COLORS (17),
since this is the first color entry generated by addtocolorlist with a
proper cbutton pointer.
I tried to trace it but you probably know better what is happening and
why.
Black and white are supposed to be allocated automatically; this is
done with "addnewcolorentry", but I see that that routine is defined
in the Tcl/Tk version only. I will track this problem down and fix it.
