OS X- quartz or not?

[Alex Rice]

In the realbasic strengths section of
http://wiki.macitworks.com/revdocs/ 
realbasicStrengthsComparedToRevolution
it says "REALBasic apps use Quartz rendering."

Right now I am running QuartzDebug.app, which comes with the MacOS X  
Devloper tools. I compiled a Rev app (using Rev 1.1.1) for 10.2 and am  
looking at it with QuartzDebug.app. The Rev app lights up like a  
christmas tree (indicating Quartz drawing) and I can tell no difference  
in the QuartzDebug output between the Rev app and say, TextEdit, which  
is a Cocoa application and which definitely uses Quartz text rendering.

Based on this anecdotal evidence I would venture that Rev apps on OS X  
do already use Quartz thanks to Appearance Manager. Can someone who  
knows Quartz well write a rebuttal for that item?
