Warning
gdk_gc_set_dashes has been deprecated since version 2.22 and should not be used in newly-written code. Use cairo_set_dash() to set the dash in Cairo.
Sets the way dashed-lines are drawn. Lines will be
drawn with alternating on and off segments of the
lengths specified in dash_list. The manner in
which the on and off segments are drawn is determined
by the line_style value of the GC. (This can
be changed with gdk_gc_set_line_attributes().)
The dash_offset defines the phase of the pattern,
specifying how many pixels into the dash-list the pattern
should actually begin.
