OK.  I've attached a patch.

Do you want this installed on master or the release branch?

Best regards,

-New font handling mechanism with font backend method
-----------------------------------------------------
-
-The new files are:
-       font.h -- header providing font-backend related structures
-               (most important ones are "struct font" and "struct
-               font_driver"), macros, and etc.
-       font.c -- main font handling code.
-       xfont.c -- font-driver on X for X core fonts.
-       ftfont.c -- generic font-driver for FreeType fonts providing
-               device-independent methods of struct font_driver.
-       xftfont.c -- font-driver on X using Xft for FreeType fonts
-               utilizing methods provided by ftfont.c.
-       w32font.c -- font driver on w32 using Windows native fonts,
-               corresponding to xfont.c
-       w32uniscribe.c -- font driver on w32, using the uniscribe API
-               to provide complex script support for opentype fonts on
-               Windows 2000 and later, or earlier versions of Windows
-               with uniscribe installed as an add-on.
-
-So we already have codes for X and w32.  For Mac it seems that we need
-these files:
-       atmfont.c -- font-driver on mac using ATM fonts, corresponding
-               to xfont.c
-As BDF fonts are currently used on w32, we may also implement these:
-       bdffont.c -- generic font-driver for BDF fonts, corresponding to
-               ftfont.c
-       bdfw32font.c -- font-driver on w32 using BDF fonts,
-               corresponding to ftxfont.c
-But, as FreeType already supports BDF fonts, if FreeType and
-Fontconfig are also available on w32, what we need may be:
-       ftw32font.c -- font-driver on w32 directly using FreeType fonts
-               utilizing methods provided by ftfont.c.
-
-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.
-       bdffbfont.c -- font-driver on FB for BDF fonts.
-
-Note: The fontset related codes are not yet matured to work well with
-the font backend method.  So, for instance, even if you start Emacs
-as something like this:
-  % emacs -fn tahoma
-Non-ASCII Latin characters will not be displayed by the font "tahoma".
-In such a case, please try this:
-
-(set-fontset-font "fontset-default" 'latin '("tahoma" . "unicode-bmp"))
