Since this question has come up before, maybe a comment should be added to the 
effect of:

/* Default value for -monitoraspect option */

so that people reading the source would realise what it's for and how to 
easily change it.

For example, I have an old 14" monitor that's 4:3, but in my quest to get as 
much desktop real estate as possible (with a >= 70Hz refresh rate) it runs at 
a resolution of 920x512, which, if calculated automatically would yeild an 
aspect ratio of 1.79:1 (or 16.17:9, a little more than widescreen) instead of 
the correct ratio of 4:3.  Sure, this is an extreme case, but common 
resolutions such as 1280x1024 are also not exactly 4:3.

Cheers,
Adam.
