/*
* xvdir.c - Directory changin', file i/o dialog box
*
* callable functions:
*
* CreateDirW(geom,bwidth)- creates the dirW window. Doesn't map it.
* DirBox(vis) - random processing based on value of 'vis'
* maps/unmaps window, etc.
* ClickDirW() - handles mouse clicks in DirW
* LoadCurrentDirectory() - loads up current dir information for dirW
* GetDirPath() - returns path that 'dirW' is looking at
* DoSave() - calls appropriate save routines
* SetDirFName() - sets the 'load/save-as' filename and default
* GetDirFName() - gets the 'load/save-as' filename (no path)
* SetDirSaveMode() - sets default format/color settings
*
* InitPoll() - called whenever a file is first loaded
* CheckPoll(int) - checks to see whether we should reload
