* New feature: New switch to set pixel resolution in map units as an 
	alternative of enlarge factor. It is pixel width for case 
	of non-square pixels. 	(-p or --pixel-resolution)
* New feature: New switch for test run. Do not download anything, just 
	compute and print number and dimensions of seams to download 
	and output image dimensions and resolution with actual settings. 
	(-t or --test)
* New feature: Log files. By default, a log file is saved with each image. 
	The file name is imagename.xyz.log, where imagename.xyz might be 
	map.tif and the log file map.tif.log for example. There is also switch
	not to create the log file. (-n or -no--log)

20060118 MapGrab 0.1.1
* Bug fix: Bash arithmetic used in inapropriate place - it roughed decimal 
	result to integer number which led to less accurate world file. The bug 
	affected significantly only maps with coordinates with small numbers, like 
	maps in geographic coordinates, or maps of regions near the coordinate axes.
	Fixed by using bc instead of bash.
* Feature improvement: The enlarge factor now can be decimal number.
