+// 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.
