No, ideally no part should be aware where the directory is ;) Actually I
would prefer it if hugin (& panotools) create all their temporary files
in a separate tmp directory (which can be deleted on hugin's exit).

I'm always annoyed when I see temporary files in my working
directories.

Probably the easiest thing would be to create a temporary directory
(using tempnam on unix) in a user specified directory (tempnam
defaults to $TMPDIR or /tmp, if $TMPDIR is not set) on startup,
and cd hugin there. 

currently, the project files contain fully qualified path names, so this
shouldn't be a problem. If we do otherwise, then I will to change
the LoadPTProjectCmd so that it creates complete filenames from relative
filenames in the project file. (And strips them down to relative ones on
saving again.)

wxFileDialog looks quite ugly on linux when compared to the kde file
dialog....

as for the pathes, maybe we should use wxFileDialog::Get/SetDirectory,
or use the directory argument of the wxFileDialog constructor
instead of change the working directory before opening a filedialog and
changing it back after closing it.

ciao
