IDE: fix again ruberband with gtk3.
DC logical functions are now disabled when using GTK3.
Apparently using XOR was still having an effect.
Use regular black pen with no logical funciton instead.

CircularBar widget changes the end angle of a "path" labeled arc according
to value of the single accepted variable.
If "min" a "max" labeled texts are provided, then they are used as
respective minimum and maximum value. Otherwise, value is expected to be
in between 0 and 100.
