Cairo drowing works fine.
I saw in gtkstyle.c that gtk_paint_box just sets background and draws
shadow. Now, if I paint shadow directly instead of box (with
gtk_paint_shadow) it works! Strange. I need to read more about these
engines/themes and try gtk_rc_* func as you suggested.

Yes, please. Thanks
