* RST file format, version 0

*
* filemark 8 bytes (contains the word "Rast")
* preamble variable length but at least 40 bytes
* glyph directory usually 127 entries
* raster data

* The Preamble

* Value fields can be 1, 2, 3, or 4 bytes long, and

* Character strings are of variable length; they are stored
* as a one byte count and then the string of characters
* (don't believe the documentation that says the strings are
* null terminated - it lies!).
