-This file contains a list of various font formats. It gives the
-reference document and whether it is supported in FreeType 2.
-
-
- file type:
- The only special case is `MAC'; on older Mac OS versions, a `file'
- is stored as a data and a resource fork, this is, within two
- separate data chunks. In all other cases, the font data is stored
- in a single file.
-
- wrapper format:
- The format used to represent the font data. In the table below it
- is used only if the font format differs. Possible values are `SFNT'
- (binary), `PS' (a text header, followed by binary or text data),
- `LZW' (compressed with either `gzip' or `compress'), and
- `BZ2' (compressed with `bzip2`).
-
- font format:
- How the font is to be accessed, possibly after converting the file
- type and wrapper format into a generic form. Bitmap formats are
- `BDF', `PCF', and one form of `WINFNT'; all others are vector
- formats.
-
- font type:
- Sub-formats of the font format. `SBIT' and `MACSBIT' are bitmap
- formats, `MM' and `VAR' support optical axes.
-
- glyph access:
- If not specified, the glyph access is `standard' to the font format.
- Values are `CID' for CID-keyed fonts, `SYNTHETIC' for fonts which
- are modified versions of other fonts by means of a transformation
- matrix, `COLLECTION' for collecting multiple fonts (sharing most of
- the data) into a single file, and `TYPE_0' for PS fonts which are to
- be accessed in a tree-like structure.
-
- FreeType driver:
- The module in the FreeType library which handles the specific font
- format. A missing entry means that FreeType doesn't support the
- font format (yet).
-
-
-Please send additions and/or corrections to wl@gnu.org or to the
-FreeType developer's list at freetype-devel@nongnu.org (for subscribers
-only). If you can provide a font example for a format which isn't
-supported yet please send a mail too.

-[1] Support should be rather simple since this is identical to `CFF' but
- in a PS wrapper.

-[2] Official PFR specification:

- http://www.bitstream.com/categories/developer/truedoc/pfrspec.html
- http://www.bitstream.com/categories/developer/truedoc/pfrspec1.2.pdf
-
- The syntax of the auxiliary data is not defined there, but is
- partially defined in MHP 1.0.3 (also called ETSI TS 101812 V1.3.1)
- section 7.4.

- for a specification given in Appendix D on pgs. 436-450. However,
- this information might be out of date; unfortunately, there is no
- PCF specification available online, and this book is out of print.
- George Williams deduced the font format from the X11 sources and
- documented it for his FontForge font editor:
