When running with a compositor the border of some applications (firefox,
chromium, zathura...) is not rendered correctly.  Initializing the highest
significant bits of the color fixes it.

way.  Consistently use font ascent+descent instead of an arbitrary font

XF86 keys support.

found and fix by Luis Henriques <henrix@camandro.org>

Spawn a window, maximize it in any way, move the cursor to a window border
that is not on the screen's edge and unmaximize again:  While the window
goes back the cursor stays at the screen's edge, i.e.  focus is lost to the
underlaying window.

Moving, resizing, tiling or snapping windows in any way always moves the
cursor along iff needed, e.g. using MS-[hjkl] to move a small window from
the center to the edge keeps the cursor within window borders -- no matter
what you do with the keyboard, focus stays on that window.

Make CM-f, CM-m, CM-equal and CMS-equal (default bindings) for toggling
full-screen mode, maximization, vertical maximization and horizontal
maximization of the current window drag the cursor along if needed as well.

* refs/heads/master:
  Fixed memory leak in xu_get_strprop.
  Prevent out of boundary write with configuration files in which too many quoted arguments are stored for other window managers.
  Allow configuring a percentage window size of the master window during htile/vtile actions. From Uwe Werler, with a few manpage tweaks.
  zap stray tabs
  Instead of using _NET_ACTIVE_WINDOW on restart, use the pointer location to determine what client to set active. Reduces a round trip for every window.
  Add support for SIGINT/SIGTERM.
  Simplify conditional construct.
  Trim event_mask to those that the root window actually needs.
  No need to lookup current client early; move to right before it is needed.
  Recommit 1.259, but now with TAILQ_FOREACH_SAFE.
  Revert previous. Causes a crash as reported by Tom Murphy.
  Simplify list markup.
  Plug two memory leaks. Also get rid of a variable that is no longer necessary.
  Remove ColormaskChange from event-mask since there's no event handler.
  Unrelated style fixes, consistency changes and sorting, appropriate dosage/removal of wrappers, simplification of name queue, client cycle joins other kb/mb bound functions.

If a client calls XSetTextProperty for a window to clear all its
properties, then allocated memory within libX11 is not freed.

quoted arguments are stored for other window managers.

The quotation handling happens within the while loop without checking if
the "end" limit has been already reached. If this happens, the final
NULL assignment leads to an out of boundary write on stack.

  Ensure the pointer stays within client bounds after a window 'snap' (to edge).
