[osflash] Know how many kb each class adds to the SWF when compiling with MTASC

[Bob Ippolito]

How does class size really help there? A library is a more or less a  
fixed size, you could find out how big it is just by throwing  
together a trivial SWF that uses it. The size of a class isn't very  
useful anyway unless it has no dependencies, what you need to know is  
the size of the entire dependency graph that class brings in (if  
you're trying to decide whether to use it or not).

It sounds like what you actually want is a tool that generates a  
dependency graph so you can find out which classes aren't used at all  
in any obvious way. Eliminating all of those could be a significant  
savings at very little cost... Unless of course dynamism/reflection  
happens to be used to find classes, in which case you'd have to  
manually add stuff to the dependency graph.

You could go even farther and eliminate dead code by removing unused  
methods and their dependencies, but that requires a lot more analysis  
and source code transformation. I guess you could get away with  
eyeballing it and manually excluding certain edges from the  
dependency graph, but that would still require source code  
transformations in order to get it to compile.
