While it's true that Apple's compositing wastes a great many clock 
cycles for minor incremental aesthetic enhancements, and it's painfully 
true that the limitations of their APIs requires developers of tools 
like Rev and SC to jump through some pretty big hoops to allow their 
developers to have default buttons rendered reliable against even 
non-Apple-sanctioned-stripes backgrounds, the actual CPU time Rev takes 
up to deal with all of Apple's nonsense was tremendously reduced several 
versions ago.

Which version are you using?  In v2.9 and the last few prior, I don't 
recall seeing any idle state exceed 15% of total CPU time (more than 
ideal, perhaps, but down several times from what it once was and may be 
able to be brought down even lower if Apple changes their compositing API).
