+// 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.
