bug#651: suggestion: replace xpm images format by png

[xah lee]

Summary: Suggesting that xpm format images used in emacs be replaced  
by png.

Detail:

In emacs, it seems the default image format is xpm.
http://en.wikipedia.org/wiki/X_PixMap

For example, the emacs logo, widget graphics, all seems to be xpm  
format at dir “etc/images/”.

The xpm image format is some 19 years old tech based on ascii text,  
very bulky. png or svg are perhaps good candidates.
