The rules for determining if the file name is absolute or relative also depends
on the file name format and the only portable way to answer to this question is
to use \helpref{IsAbsolute}{wxfilenameisabsolute} method. To ensure that the
filename is absolute you may use \helpref{Normalize}{wxfilenamenormalize}. There
is also an inverse function \helpref{MakeRelativeTo}{wxfilenamemakerelativeto}
which undoes what \helpref{Normalize(wxPATH\_NORM\_DOTS)}{wxfilenamenormalize}
does.
