The problem is that code which is formatted to look pretty in source form 
doesn't neccessarily look pretty when displayed with preview-latex (e.g. 
the images created by preview-latex often are much smaller than the 
corresponding source). What I want is a tool that formats only for on 
screen viewing. Maybe it could even preserve the original format as e.g. 
the longlines mode does.

Not applicable since it returns the width of a char measured in columns, not 
in pixels.

Has the same problem as char-width.

Also seems to use columns for measuring distances.

I don't use XEmacs.

Unfortunately, I couldn't find a command that returns the width in pixels of 
a certain character in the default font. But maybe I can get that 
information via an external tool. Any ideas?
