// 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.
