 // AeroTooltipManager
 //
 //  Default Windows tooltips are broken when using our custom window frame
 //  - as soon as the tooltip receives a WM_MOUSEMOVE event, it starts spewing
 //  NCHITTEST messages at its parent window (us). These messages have random
 //  x/y coordinates and can't be ignored, as the DwmDefWindowProc uses
 //  NCHITTEST  messages to determine how to highlight the caption buttons
 //  (the buttons then flicker as the hit tests sent by the user's mouse
 //  trigger different effects to those sent by the tooltip).
 //
 //  So instead, we have to partially implement tooltips ourselves using
 //  TTF_TRACKed tooltips.
 //
 // TODO(glen): Resolve this with Microsoft.
