//*** autohide -- design note
//
// here's an overview of how we do autohide. see the code for details.
//
// only a few routines really know about it. their behavior is driven
// by '_fHiding'. when FALSE, they behave normally. when TRUE, they
// do alternate 'fake' behavior.
//
// a 'real' or 'normal' rect is the full-size rect we display when not hidden.
// a 'fake' or 'tiny' rect is the very thin rect we display when hidden.
// (plus there's a '0-width' rect we register w/ the system when we're hidden).
//
// more specifically,
//
// when fHiding is TRUE, a few routines have alternate 'fake' behavior:
// _ProtoRect returns a 'tiny' rect rather than the 'real' rect
// _NegotiateRect is a NOOP (so we don't change the 'tiny' rect)
// _SetVRect is a NOOP (so we don't save the 'tiny' rect)
// AppBarSetPos is a NOOP (so we don't set the 'tiny' rect)
// plus, a few routines handle transitions (and setup):
// _DoHide hide/unhide helper
// _MoveSizeHelper detects and handles transitions
// _HideReg register autohide appbar w/ 0-width rect
// and finally, a few messages trigger the transitions:
// unhide WM_NCHITTEST on the 'tiny' rect starts the unhide.
// actually it starts a timer (IDT_AUTOUNHIDE) so there's a
// bit of hysteresis.
// hide WM_ACTIVATE(deact) starts a timer (IDT_AUTOHIDE)
// which we use to poll for mouse leave events. again, there
// is some hysteresis, plus some additional heuristics for hiding.
// WM_ACTIVATE(act) stops the timer.
//
// #if 0
// we also have 'manual hide'. manual hide differs from autohide as follows:
// autohide never negotiates space(*) , manual hide always does
// autohide is focus- and cursor- driven, manual hide is UI-driven
// (*) actually it negotiates space of '0'.
// e.g. 'manual hide' is used for the BrowserBar (e.g. search results).
// however for now at least 'manual hide' is simply a ShowDW(FALSE).
