New font handling mechanism with font backend method
----------------------------------------------------
-The configure script, if invoked with "--enable-font-backend", checks
-if libraries freetype and fontconfig exist. If they are both
-available, macro "USE_FONT_BACKEND" is defined in src/config.h. In
-that case, the existence of Xft library is checked too.
-
The new files are:
font.h -- header providing font-backend related structures
(most important ones are "struct font" and "struct
ftw32font.c -- font-driver on w32 directly using FreeType fonts
utilizing methods provided by ftfont.c.
-And, for those to work, macterm.c and macfns.c must be changed by the
-similar way as xterm.c and xfns.c (the parts "#ifdef USE_FONT_BACKEND"
-... "#endif" should be checked).
-
It may be interesting if Emacs supports a frame buffer directly and
has these font driver.
ftfbfont.c -- font-driver on FB for FreeType fonts.
