SYNOPSIS

DESCRIPTION

       tickit_pen_has_attr() tests whether a pen instance has a given attribute defined on it. It
       returns true if the corresponding tickit_pen_set_*_attr() function has been  called  since
       construction, or the last time it was cleared. This is true even if the attribute has been
       set to its default value.

       tickit_pen_nondefault_attr() tests whether a pen instance has a  given  attribute  defined
       with  a  non-default value. It returns true if the attribute is set to a value that is not
       the default, or false if the attribute is absent, or set to the  default  value  for  that
       attribute type.

RETURN VALUE

       tickit_pen_has_attr() and tickit_pen_nondefault_attr() return a boolean.
