HISTORY for PICFIB:

V1.0	released on 1994.11.06

V1.0a	bugs fixed since V1.0
	-drawing of buttons in TOOL window improved (vswr_mode)
	-using lists that contain invalid pathnames caused bus error
	 if TOOL window was opened (NULL test)
	-error messages that contained a long pathname caused an
	 address error (increased buffer+strncat)
	-color reducing was buggy (palette compressing did not work)
	-GIF files were rejected sometimes (version check was buggy)
	-Owner drawn controls were sometimes invisible in 256 color modes
	 (vst_color was missing)

	improvements since V1.0
	-speed up of GIF loader by 10-20%
	-changed internal memory management (reduced malloc calls)
	-changed internal window management
	-toggle picture & default palette with UNDO key
	-toggle tags with keyboard (keys 1-4)
	released on 1995.04.29
	
V1.0b	bugs fixed since V1.0a
	-fast GIF loader couldn't handle several GIF89 extensions
	-internal memory management was not consistent, memory was
	 not released any more. 
	-when viewing pictures in monochrome resolutions suddenly 
	 dithering was disabled, because some buffers weren't being
	 released
	 
V1.1	bugs fixed since V1.0b
	-when cancelling a load while a list was already loaded a bus
	error occurred (current list was released BEFORE the OK to 
	load a new one was given) 
	
	improvements since V1.0b
	-added TIF support
	-added export of lists
	
V1.1a   bugs fixed since V1.1 (many discovered by Joerg T.)
	-closing of bitmap windows doesn't restore palette while tool
	dialog was open (reimplementation of handle_wind_close)
	-closing a bitmap window opened by browsing through the list
	and selecting "Slideshow" caused bus error
	(global TV was not reset on close)
	-added "*.*" wildcard to current path when opening the file
	select dialog for "New List...". Seemed to cause problems
	with FREEDOM file selector.
	-when allocation of picture failed, VDI buffer wasn't released
	any more (get_picture)
	-if there wasn't enough memory to allocate VDI transformation 
	buffer, a bus error occured (image_convert, NULL test)
	-if a file caused an error condition during slideshow, the
	slideshow was aborted. (different return codes added)
	
	improvements since V1.1
	-command line arguments are processed. So it's possible to 
	set PICFIB as application to display various picture 
	formats.
	-progress bar is displayed for loading, dithering, color 
	reduction
	-added JPEG picture support. (Need test of low memory 
	conditions with floppies)
	-PICFIB now handles the AP_TERM message, causing the program
	to terminate during shutdown. (Magic>2.0,Mint)
