The supplied (default) 'tuxpaint.cfg' is now empty, but is safely appended
to by the NSIS script. NSIS now has a Mode (Windowed|Full-Screen) and a
Resolution (640x480|800x600) option which append the following lines to
'tuxpaint.cfg':
fullscreen=$mode
nofancycursors=$mode
800x600=$res
[Where $mode and $res are "yes"|"no".]
The added file 'options.ini' contains the GUI layout for the new page.
'prebuild.py' generates the .mo files, converts the text documents to CRLF
format (it only touches the files if they need converting) and builds
'filelist.inc' which is used by NSIS. This avoids including CVS folders.
