[Image-SIG] documentation error and feature request

[Andrew Harrington]

A documentation error and suggestion for pildriver:

The online pildriver documentation
http://www.pythonware.com/library/pil/handbook/pildriver.htm
omits the float parameter in the sharpness method description, and I 
would guess there are similar issues in lighten and others.

A feature request:
Currently you can resize to specific dimensions in pildriver.  I 
frequently want a half size picture, whatever the original size.   It 
would be good to be able to scale an image by a factor.  That could be 
done directly with a variation on resize or an operator on a size pair

scaleby <float:factor> <int:x> <int:y>
which produces the dimensions scaled by factor and rounded and converted 
back to int's

Thanks!  I love PIL.
