WindowMenuAccessor returned strange alpha values if compiled
with 'g++ -Os'; unholy black magic happens if template<int> faces
functions returning only 'usigned char'.
reasons:
* fixes#1732115, allows to have chatwindows on another workspaces and reach them via :NextWindow (urgent=yes)
* old behavior can be achieve by using the (workspace=[current]) pattern
a 'BidiString' holds both the logical content and the visual reordered
version of the content of a string. this helps to reduce the number of
calls to reorder the string before drawing it (as introduced in the patch
from Ken Bloom) and to be more consistent in menus and textboxes (drawing
cursors and underlining text).
As noted in the previous commit, StrictMouseFocus now works as advertised:
Focus follows mouse on every EnterNotify event (except when the "ClientMenu"
closes or during alt+tab window cycling)
This is not actually implemented yet, but from now on, "MouseFocus" means:
Focus follows mouse only when you are moving the mouse, any EnterNotify events
caused by non-mouse operations (window closing, keycommands, changing
desktops) will *not* shift focus
And once fully-implemented, "StrictMouseFocus" will mean:
Focus follows mouse on every EnterNotify event (except when the "ClientMenu"
closes or during alt+tab window cycling)
This will be used to avoid some situations where an EnterNotify event should not
focus the window beneath the mouse cursor. For example, when a menu (or any
window for that matter) is unmapped, focus should not pass to whatever window is
beneath the current location of the mouse cursor, but to the previous window in
the focus list.
This was first noticed when using the ClientMenu feature with
focus-follows-mouse on -> The focus would always end up on the window beneath
the mouse pointer, not the window selected in the menu.
