In dwm.c function declarations are in alphabetical order except for
updategeom(). There doesn't appear to be any reason for this, so this
patch corrects that, and now all function declarations are in
alphabetical order.

the bug in the dwm man page is an (ancient) Java issue.

Thanks David and quinq for the patches and feedback!

Thanks Christopher Drelich <cd@cdrakka.com>

Reported by Kernc, thanks!

"This makes a particular program that uses libwnck [1] fail after:

    Wnck-WARNING **: Property _NET_WM_NAME contained invalid UTF-8

in this code [2] because the returned string contains a '\0' and the
documentation for g_utf8_validate() [3] explicitly states that when
string length is provided, no nul bytes are allowed."

It is not entirely clear it is incorrect, other WM's seem to not
NUL terminate it either though.

This is useful for configuring compositors to ignore the status bar
window.

The previous patches introduced some unclean space-based indentation
patterns. This patch fixes them.

This also fixes a bug where client windows only switch to floating mode when the
mouse is dragged in one specific direction.

Before this change it is not possible to press a button in a client on the first
click if the client is not yet focused. The first click on the button would
only focus the client and a second click on the button is needed to activate it.
This situation can occur when moving the mouse over a client (therefore focusing
it) and then moving the focus to another client with keyboard shortcuts.

After this commit the behavior is fixed and button presses on unfocused clients
are passed to the client correctly.

- unify multi-line expression alignment style.
- unify multi-line function call alignment style.
- simplify client moving on monitor count decrease.
- clarify comment for focusin().
- remove old confusing comment about input focus fix in focusmon(). The
  explanation is already in the old commit message, so no need to keep it in the
  code.
- remove old comment describing even older state of the code in focus().
- unify comment style.
- break up some long lines.
- fix some typos and grammar.

thanks Markus Teich and David!

- better scaling for occupied tag squares.
- draw statusline first to omitt some complicated calculations.

Configuring geometry before applying rules makes it possible to have
more complex constraints in applyrules that depend on the initial window
dimensions and location.

patch provided by Bert Münnich <ber.t_AT_posteo.de>, thanks!

True, False are X11-specific (int), make sure to use c99 stdbool for
program-specific things.

Some clients try to set _NET_WM_STATE_FULLSCREEN even when the window is
already in fullscreen.
For example, c->oldstate was set two times in a raw and window would
then always be floating.
We must check that it's not the case before processing it.

important:
- drw_rect: didn't use w and h, change the dwm code accordingly.
- drw_text: text is NULL is not allowed, use drw_rect().

- signal: print error string.
- die: start message with lower-case (consistency).
- bump version to 2015.

dmenu uses Xft now (soon to be released).

"Limit the amount of updates when resizing or moving a window in floating
mode to 60 times per second. This makes resizing and moving alot smoother
and by limiting it it also uses alot less resources on my machine.

however renamed theme into scheme resp. Theme into ClrScheme
