6e664f49b1 Guard font functions against invalid font ids. These arguably should never be passed, but this prevents freezes. Fixes FS#12400

e299eb3ea3 Add functions font_set_ui() and font_get_ui(). The font returned by FONT_UI used to be fixed at zero but since buflib-fonts (r30589) can be different, depending on the order of loads and unloads. Fixes broken behavoir in virtual keyboard (FS#12336), lyrics player (FS#12306), and hopefully, FS#12337

9edd6d4ee9 Anti-Aliased Fonts support. 
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).

faaf431d32 Accept FS#11567 by Fred Bauer - better memory management for the skin fonts 
%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)

9c0b2479f7 Rockbox as an application: add get_user_file_path(). 
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

559c56905e Font improvements: Fix bug that caused some fonts to be rendered garbled on custom builds with MAX_FONT_SIZE > 64k (closes FS#10844). Simplify version check. Use void pointer and explicit casting for the offsets to make it clearer that they may be of different sizes, add a comment too. Use uint16_t in stead of short in some places for consistency. Replace magic number with meaningful define.

7682cb5ca8 FS#10720 - Support for displaying diacritic characters 
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.
