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

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."

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).

- Removed "antialias"-option completly, to enable/disable "antialias"
use either <fontname>:antialias=<bool> in the style or use
Xft.antialias: <bool> in your .Xdefaults
- Added new styleresources:
*.font.effect: <halo|shadow>
*.font.shadow.x : <int> - shadow x offset
*.font.shadow.y : <int> - shadow y offset
*.font.shadow.color : <color> - color of shadow
*.font.halo.color : <color> - color of halo
- Removed 'shadow' and 'halo' options from fontdefinitions:
!! Style authors have to update their styles !!
- Simplified XmbFontImp to not try all possible fonts to match locale
- Style authors may specify multiple fonts:
<font1>|<font2>|<font3>
if loading of font1 fails, fluxbox probes <font2>, etc. The last font is
"fixed". Hints for style authors:
- if xft tries to load a font it will _ALWAYS_ return a valid font,
it doesnt have to look like the one you want to have, read more
about it: http://fontconfig.org/fontconfig-user.html
- export XFT_DEBUG=1 before running fluxbox helps to see
which fonts are picked.
eg:
*.font: Verdana,Arial-12:antialias=true|-artwiz-snap-*-
if fluxbox is compiled with xft this will NEVER try to
load "-artwiz-snap-*-" since xft gives for sure a font,
most likely Verdana or Arial but noone knows. So, if
fluxbox has no xft support the first fontpattern fails
and fluxbox tries the next one, which might be successful.
if everything fails, it will use "fixed"
- Added caching of fonts, fonts are only loaded once.
- Fixed #1090902 (slow utf8 start)

systems had problems before. with this change fluxbox should compile on such
old compilers.

besides xpm. to get imlib2 support in fluxbox one has to
./configure --enable-imblib2
default is disabled. a fluxbox-binary that supports imlib2 will have
IMLIB2 in "fluxbox -info"-output
explanation to the changed files:
* xft.m4 -> acinclude.m4 + added ac_path_generic.m4
(from http://ac-archive.sourceforge.net/Miscellaneous/ac_path_generic.html)
* configure.in, Makefile.am, src/FbTk/Makefile.am changed to handle
imlib2-support
* Font.cc/hh Image.cc/hh App.cc fluxbox.cc consistent way of init for global
stuff for fonts and imagehandlers.
* rest of changes just add the imlib2-code, pretty straightforward

primary problem was to use utf8 when in fact the FontSet wasnt
utf8.
