Fix the bad rendering of text on OSX

Browse Source 
The problem was because I added double buffering to reduce
flicker on Windows.  But, OSX already does its own buffering
and adding more causes text to be rendered incorrectly.

This happened a long time ago on the track panel and when
Bill gave the screenshot, my aging brain slowly remembered
the cause.
