This enables Rockbox to render anti-aliased fonts using an alpha blending method.
The input font bitmaps are 4bit, i.e. 4x larger, but the metadata size stays the same.
A tool, convttf, for converting ttf fonts directly to the Rockbox fnt format is provided.
It has a useful help output, but the parameter that works best is -c1 or -c2 (2 for larger font sizes).

%Fl now takes an optional 3rd param which is the number of glyphs to cache (default to 256). the smaller the number, the less ram will be used (i.e using 15 for a font which only shown numbers is a good idea)

For RaaA it evaluates user paths at runtime. For everything but codecs/plugins it will give the path under $HOME/.config/rockbox.org if write access is needed or if the file/folder in question exists there (otherwise it gives /usr/local/share/rockbox).
This allows for installing themes under $HOME as well as having config.cfg and other important files there while installing the application (and default themes) under /usr/local.
On the DAPs it's a no-op, returing /.rockbox directly.
Not converted to use get_user_file_path() are plugins themselves, because RaaA doesn't build plugins yet.

1) seperate UI font for the remote and main displays
2) allow individual skins to load additional fonts for use in the skin (Uo to 7 extra in this first version) see CustomWPS for info on how to load a font in the skins.
Code should always use FONT_UI+screen_number to get the correct user font

This commit corrects the display of diacritic characters, which exist in many
languages. Hopefully, it will make Rockbox much more usable for users of these
languages.
Diacritic information (which used to decide whether a given character is
diacritic or not) is taken from the Unicode Standard, Version 5.2.
This feature does not affect drawing performance much, as the diacritic
database is cached (simple MRU mechanism).
There may be room for further performance, footprint, and
code-reuse wise improvements, that could be worked on in the future.

The following patch makes loadable fonts actually work (finally!).
It took me quite a while, but I finally figured out why the sim
worked and the target didn't: the SH1 processor won't read
longwords from a shortword alignment... I had to rev the .fnt
file to version 1.1 (requires remaking *.fnt files) in order
to fix this. Please apply the following patch completely.
It's diffed against the latest CVS.
I've also attached rockbox-fonts-1.1.tar.gz which includes
known working *.fnt files, including a courB08 system.fnt,
for demonstration.
Now the real work can begin... Although the new
system.fnt will work fine, if you try going to a really
big font (try copying courB14.fnt to system.fnt), then
you will find that it comes up and works in tree mode,
but will crash the system when going into WPS
mode... I'm sure this is because of the low-level
lcd_bitmap not clipping properly when given a too-large
bitmap, which the characters become. I haven't yet
tried to debug the low-level driver. Of course, it all
works on the sim...
So the apps developers will now have to make sure that
all apps screen sizes may vary according to the loaded font.
The font height can be gotten through the lcd_getfontsize API.
Files patched in fonts-6.patch
1. apps/menu.c - LCD_PROPFONTS error (2nd resubmission on this, please checkin)
2. firmware/font.c - fixes and reformatting. Please check this in as is,
my vi editor requires more reformatting changes since I left tabs in the
file, these are removed now (2nd resubmission on this, please checkin)
3. firmware/fonts.h - doc change on .fnt file format, .fnt version
number incremented.
4. firmware/loadfont.c - fixes to load font properly, typedefs
removed.
5. firmware/system.c - lcd_setfont(FONT_SYSFIXED) before
issuing error, otherwise font may not exist.
6. tools/bdf2c - fixes for correct output when filename starts
with a number, as well as when no DEFAULT_CHAR in .bdf
file. (2nd resubmission on this, please checkin)
7. tools/writerbf.c - fixes for bugfixed fontfile format.

Rotates the font bitmaps only once at font_init() time, with some source
cleanup to rockbox standards.
