Add option to use vibrancy for terminal background [was: Blur - extremely low performance on Mountain Lion + Retina Display]

What steps will reproduce the problem?
- Enable Blur, with some transparency
- The more blur, the more lag (a simple test is to drag the window around, increase blur and try again)
What version of the product are you using? On what operating system?
iTerm - 20120203, OS X 10.8 GM, MacBook Pro Retina
Please provide any additional information below.
The lag is crippling! The whole OS slows to a crawl, even (to a lesser extent) when the terminal window is on a separate desktop, or in the background. Seemingly more so over time...could it be a memory leak?
The problem was observed using the integrated intel 4000 graphics card, I was unable to test with discreet at the time of reporting (I'll update once I test)
I do not have access to a non-retina display macbook with Mountain Lion, so I'm not sure if the problem is Retina-specific of ML-specific. Hopefully someone else can fill in the blanks.
