The old code did not brighten up "pure" colors like "red", "green" and "blue"
at all. The new code use a different precomputed LUT which is based upon
simplified vector math, see the comments in FbTk/ColorLUT.cc

Stupid typo.

* Calling Timer::setTimeout() from within Timer::start() might lead to ugly
behavior (as experienced in bugs #3590078, #3600143, etc; see commit
4d307dcd10af9d817ff5c05fc40ae7487564cb31, fixes the problem partially).
* Stop a timer first, then call the handler (via Timer::fireTimeout()). A
given handler might call Timer::start() again, which (re)adds the Timer
to the control list .. the following Timer::stop() would remove it again.
* Use 'm_start' as indicator if timer is running.
* Move the (now quite short) code of ::addTimer / ::removeTimer
into the Timer::start() and Timer::stop() functions.

Testing bits-per-pixel in the inner loop is suboptimal, especially since
that value does not change. A little helper macro helps to keep the code
readable, also improves the situation for StaticGray and PseudoColor.

With commit 541c8c4 we switched from an (manually) ordered list to a
std::set<> to handle the active timers. The code which checks for overdue
timers now traverses and modifies the std::set<> in place. This might
lead to an infinite loop. Examples of such bad behavior are "flickering of
the tooltip" (bug #3590078) or crashes (bug #3600143) or just insanely high
cpu load when autoraising windows or submenus.
We now make a copy of the std::set<> traverse this instead of the original.

'filename' might contain a '~' which has to be expanded to work for
regular system calls. We expanded 'filename' already but then did not use
it. Fixes bug #3576586.

* much more readable and easier to read code
* smaller code
* reduced binary size due to removed big lookup-table for square root
* simple 'optimizations (lookup tables, packing of data), nothing too fancy

The old formula for vertical align text inside FbTk::TextButton ('height/2 +
font_ascent/2 - 1') produced not always good looking results, escpecially
when different fonts are involved (eg, ClockTool and WorkspaceName have
different fonts and font-sizes).
'(height - font_ascent) / 2 - 1' produces better results.
Additional changes:
* added ASCII-Art to document the involved entities when calculating the
baseline
* rewritten tests/testFont.cc to accept multiples texts and multiple
fonts
* removed some internal parts of FbTk::Font from the public interface

timer list
Setting a new timeout on a running FbTk::Timer must remove it from the timerlist,
otherwise the list is not ordered correctly anymore. So, we stop the running
FbTk::Timer, set the new timeout and restart it.

gettimeofday() is subject to be changed on daylight-saving or to ntp-related
(think leap-seconds). even worse, it is subject to be changed BACK in time. this
is hard to fix correctly (see commit 45726d3016e and bug #3560509). it is
irrelevant for timers to know the nano-seconds since the epoch anyways.

The same logic had been already implemented for texture resources.

Found with cppcheck:
"Prefix ++/-- operators should be preferred for non-primitive
types. Pre-increment/decrement can be more efficient than
post-increment/decrement. Post-increment/decrement usually
involves keeping a copy of the previous value around and adds
a little extra code."

if pos is not npos, it will always be less than filename.size().
However, the access later is only safe if there is a character
after pos, which would require pos + 1 to be less than filename.size.

calling imlib_set_cache_size() before a context is created by fluxbox creates
an 'unknown' context. that one is never freed at shutdown.

93924af160ea303c94a2576b0e57a04e94c9228c might corrupt memory with gcc-4.6.1 when
finishing fluxbox (clicking 'exit', sending it a SIGINT). Allthough the order, in which static / global
objects are initialized is undefined (at least between separate compilation units), the order in
which they are destroyed is well defined: in reverse order of initialization.
this means, that if 'ScreenImlibContextContainer contexts' (of ImageImlib2.cc)
gets initialized AFTER 'ImageImlib2 imlib2_loader' of Image.cc, it gets destroyed before
imlib2_loader. When that happens, ~ImageImlib2() works on a destroyed object.
(That lead to '* glibc detected * fluxbox: corrupted double-linked list: 0x0000000000dd2710 ***'
later on in 'iconv_close')

fluxbox now properly displays windows that require ARGB visuals when
an external compositor is running. This was done by creating the
container window with the correct visual and colormap when needed.
Closes #2874629
