libsaxsdocument
===============
 * doxygen docs
 * language bindings: Fortran, C++, Python(?)
 * more formats
 * more testcases

libsaxsview
===========
 * doxygen docs

saxsview
========
 * save/restore last working directory
 * watch files for changes (?)
 * allow for probability curves
 * allow for annotations, e.g. freely placeable labels,
   on the plot area
 * configurable plot layout (see below)
 * save/restore a particular configuration into/from
   plot-description files (based on QSettings, ini-format)
 * show current coordinates (and values in images) in status bar
 * make legend inside plot freely moveable
 * bounding box: do not take error bars into account if they are disabled
 * store/restore printer selected last

 * if a .pdb-file shall be openend, run crysol
   to display its scattering pattern
 * make file handling configurable - this kind of file, that action


Configurable Items in saxsview
------------------------------
All fonts shall individually be configurable in family,
size and style (bold, italic).

Color selection should allow alpha channels.
