Summary: [UPDATED] Improve text rendering in swf8, add api for text  
rendering hints

New Features: new api on LzText to control swf8 rendering parameters

Bugs Fixed:

Technical Reviewer: max (pending), ptw (pending)
QA Reviewer: (pending)
Doc Reviewer: (pending)

Documentation:

Added four new virtual attributes to LzText, each of which control an  
aspect
of advanced text rendering in swf8: sharpness, thickness, antiAliasType,
and gridFit. These attributes only have an effect in swf8; in other  
runtimes,
they will quietly be no-ops. We provide set/get for each of these new  
virtual
attributes, and give them good initial and default values.

Note that the default values are set such that <text>boring</text> will
use normal rendering, because advanced rendering causes a performance  
hit. To
get the advanced rendering, just set antiAliasType="advanced" on the  
text
object.

Added capability "advancedfonts" for these text rendering attributes;  
made it
true for swf, false for dhtml.

Release Notes:
To get advanced rendering in swf8, just set antiAliasType="advanced"  
on a text
object.

Details:

Tests:
http://localhost:8080/legals/test/lztest/lztest-textstyle.lzx? 
lzr=swf8&debug=true
sussurate should look good but blurry. mimsy borogroves should look  
not great.
"i should look bad" and "pixel gridfit" should have weird color bands  
around the text
http://localhost:8080/legals/test/lztest/lztest-textstyle.lzx? 
lzr=swf8&debug=true
all the text should look the same
"ant doc" still works
http://localhost:8080/legals/test/text/renderingcomparison.lzx?lzr=swf8
  should look really cool, with each of the text objects in the top  
three
  rows looking slightly different.
