fonts: Fix regression(s) caused by c23ce62.

2014-01-26T13:01:48+00:00

The builtin sysfont does not have an associated buflib_alloc_data
(because it's builtin right?). font_get_{width,bits} accessed a field of
it for all fonts which crashed on some systems but not on mine.
Solution: Move this field to struct font directly.

The cache size calculated was also busted.

Fixes FS#12944 and most likely FS#12938.

fonts: Do not unload completely on USB.

The font engine can now perform cache lookups even if the font file is
closed, if the font was disabled with the new font_disable_all() function.
It is highly probable that the lookup succeeds but in the cache-miss case
a blank, full-width glyph will be returned.

Increase MAXUSERFONTS to 12.

2013-04-01T15:30:38+00:00

In the modern everything-can-be-skinned world, themes are beginning
to hit the limit of 8 fonts (which includes sysfont). Increasing this
to 12 will allow some headroom, at the cost of a bit more RAM usage
(about 20 bytes per extra possible font, so about 80 bytes total here)

glyph_cache_save should be static

FS#12293 Global default glyph setting in System > Limits > Glyphs To Cache. Defaults to 250. This saves a lot of RAM while still allowing non-English users to have adequate glyph coverage.

Redo r30826 (and hopefully not reintroduce font issues) which cleans up the font API. FONT_UI is deprecated, use screens[screen].getuifont() instead (and .setuifont() to set it after a font has been loaded)

git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30932 a1c6a512-1295-4272-9138-f99709370657

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

Provide font_lock(). Font_get_bits() or ..width() may have to read glyph cache misses from disk so provide a means to lock the buflib memory during the wait.
