_Font Manager_ interface
========================

_Font Manager_ interface for SGI workstations.

This module provides access to the IRIS _Font Manager_ library.  It is
available only on Silicon Graphics machines.  See also: _4Sight User's
Guide_, section 1, chapter 5: "Using the IRIS Font Manager."

This is not yet a full interface to the IRIS Font Manager.  Among the
unsupported features are: matrix operations; cache operations;
character operations (use string operations instead); some details of
font info; individual glyph metrics; and printer matching.

It supports the following operations:

`init()'
     Initialization function.  Calls `fminit()'.  It is normally not
     necessary to call this function, since it is called automatically
     the first time the `fm' module is imported.

`findfont(fontname)'
     Return a font handle object.  Calls `fmfindfont(FONTNAME)'.

`enumerate()'
     Returns a list of available font names.  This is an interface to
     `fmenumerate()'.

`prstr(string)'
     Render a string using the current font (see the `setfont()' font
     handle method below).  Calls `fmprstr(STRING)'.

`setpath(string)'
     Sets the font search path.  Calls `fmsetpath(STRING)'.  (XXX Does
     not work!?!)

`fontpath()'
     Returns the current font search path.

Font handle objects support the following operations:

`scalefont(factor)'
     Returns a handle for a scaled version of this font.  Calls
     `fmscalefont(FH, FACTOR)'.

`setfont()'
     Makes this font the current font.  Note: the effect is undone
     silently when the font handle object is deleted.  Calls
     `fmsetfont(FH)'.

`getfontname()'
     Returns this font's name.  Calls `fmgetfontname(FH)'.

`getcomment()'
     Returns the comment string associated with this font.  Raises an
     exception if there is none.  Calls `fmgetcomment(FH)'.

`getfontinfo()'
     Returns a tuple giving some pertinent data about this font.  This
     is an interface to `fmgetfontinfo()'.  The returned tuple contains
     the following numbers: `('PRINTERMATCHED, FIXED_WIDTH, XORIG,
     YORIG, XSIZE, YSIZE, HEIGHT, NGLYPHS`)'.

`getstrwidth(string)'
     Returns the width, in pixels, of STRING when drawn in this font.
     Calls `fmgetstrwidth(FH, STRING)'.
