[Seaside] html images

I'm no expert, but I can share the experiences of a colleague who has  
been evaluating Squeak primarily from the  perspective of its  
usefulness for building a graphically intense application.

He experimented with PNGReadWriter and with ImageReadwriter and  
reported both of them distorted images pretty badly. (His  
characterization). He concluded after some effort that Squeak cannot  
be used for the kind of app he had in mind. I've seen/heard rumblings  
from time to time on the main Squeak list that the graphics engine in  
Squeak doesn't lend itself well to antialiased rendering of text and  
images but I've had zero experience of my own with it.
