[SoC] HTML Rendering Projects

[Todd Blanchard]

I'm getting the feeling from reading the comments on the proposals to  
build HTML viewer widgets that the other mentors don't quite  
understand the point of the project.  Since I proposed it, allow me  
to explain.

I wrote a modern HTML/XHTML/CSS parser with associated DOM which can  
be found at: http://www.squeaksource.com/htmlcssparser

It is used to implement http://badpage.net - a web page standards  
checker.  It produces an decorated DOM that models HTML/XHTML.  The  
decorations are the CSS rules - it can match CSS selectors to DOM nodes.

So the really hard work of handling 'wild' HTML and CSS is done.  All  
the project seeks to do is build renderer using a Morphic widget  
hierarchy that implements the CSS box model layout and visually  
represents the DOM.

There are probably adequate Morphic widgets already available to do  
most of this, I think a table widget might need to be implemented.   
The student will need to implement builder to build/configure the  
morphs.

Key skills are - builder pattern, GUI development experience (any  
GUI, really).  Parsing is not necessary and we are not trying to  
build a whole browser.
