Building with image support

[Eric Lilja <mindcooler@gmail.com>]

Hello, I've been building emacs on windows for a few year now but I have 
always built it without image support. Anyway, I grew tired of looking 
at the ugly toolbar under windows, compared to my linux installation, so 
I set out to learn how to build emacs under windows with image support.

I managed to build it with xpm support and as long as emacs can find the 
  xpm dll I get nice looking toolbars. Good!

However, I noticed that emacs can be built to support not only xpm, but 
also png, gif, tiff and a few other image format. I set my configure 
script to pass --without-tiff, --without-png and so on so it doesn't 
test for any other format than xpm.

My question is this: What am I missing without png support, without tiff 
support etc? I only work with text with emacs, 90 percent of the time 
programming. My original wish has been fullfilled, which was nice 
looking toolbars on windows, but I wanted to know if it might be a good 
idea to build emacs with support for the other image formats as well. 
But if it doesn't matter to what I do with emacs, I don't want to 
complicate my "build environment" unnecessarily.

Also, I noticed that my build script doesn't work anymore when the jobs 
parameter is passed to make (on windows, trunk), but I will post a 
separate message about that later today I hope.
