Ok, and because this removes the setting of the frame's garbage flag
from the `updateFrameSize` function and moves it to when it receives
the `windowWillResize` event, I should only expect to see painting
issues after a frame's size is changed I would imagine.
Does anyone know if there are more ways to change a frame's size than
`set-frame-parameter`, a mouse drag or AppleScript?

Thanks, I was thinking about double buffering--painting both the clear
and the next paint on the same buffer before swapping it in, but I'm
sure that's much more simplistic than what is actually happening.
