[Image-SIG] Fixes for PIL enhancers

[Robb Shecter]

Hi all,

I having seen postings on this, so I thought I'd ask:  

The ImageEnhance module in PIL 1.1.3 is pretty rough  For example, most 
functions don't implement the full API (ie. being able to desaturate but 
not oversaturate colors in an image).

So I've implemented them all.  :-)  Was this wasted work?  Has it been 
fixed up yet?

Thanks!
Robb
