.SH DESCRIPTION
\fBtickit_pen_has_attr\fP() tests whether a pen instance has a given attribute defined on it. It returns true if the corresponding \fBtickit_pen_set_*_attr\fP() 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.
.PP
\fBtickit_pen_nondefault_attr\fP() 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.
.SH "RETURN VALUE"
\fBtickit_pen_has_attr\fP() and \fBtickit_pen_nondefault_attr\fP() return a boolean.
