Cache the NSLayoutManager etc. of the text object If you check out last
years WWDC talks, Doug Davidson gave a talk about speeding up text
drawing.

I am writing a cocoa program that requires text to be rendered
quickly to a view. The cocoa text rendering calls are too slow.
The quartz text calls do not support (I think) complicated text
handling like multiple fonts/colors on one string of text and the
antialiasing on the postscript fonts is soft/blurry when compared to
the cocoa antialiasing. What is the fastest way to draw text to a
CGContext? Is it using the ATSUI toolbox?
Is this rapidly-changing text, or do you need to render the same text
frequently?
