[ansel] Image editing functions question

[Heath S. Hendrickson]

Chuck, I noticed that you got the image editing functions working again 
(at least watermarking).  I also noticed that they now act on the 
original file and not the screen resolution image.   My question, is 
there a way to scale the size of the font based on the overall image 
proportions?  I'm using 3000x2000 images (the native resolution of my 
camera) and the font is a little small to be legible at much less than 
100% scaling of the image.  I looked at the Image.php file, but it 
wasn't apparent to me where or how to change the font size.  It looked 
as if it was dependent on the font being selected (arial).

Thanks,
heath
