How do I set the text color of a Cocoa tooltip?
I am using `BGHUDAppKit` for an outline view within a HUD-style (black) `NSPanel`.  As such the text in my outline view cells is light gray or white.  Unfortunately this means that when I hover to bring up a tooltip for a cell's value, it shows up as light gray text on yellow, which is illegible.  

How can I set the text color for the tooltip, or is there a way that I can modify the control itself (without changing its appearance) to work better with the tooltip mechanism?
