NAME
     glutStrokeWidth -- Returns the width in pixels of a character in a given font.

LIBRARY
     OpenGLUT - fonts

SYNOPSIS
     #include <openglut.h>

     float
     glutStrokeWidth(void *fontID, int character);

PARAMETERS
      fontID	 A GLUT stroked font identifier.

      character  A character code.

DESCRIPTION
     This function reports how far the model space origin will advance if you putput this  char-
     acter  in the font named by  fontID.   Not all letters will use their full width, especially
     in fixed-width fonts.

     Returns 0 if  character  is out of range or if the  fontID  is invalid.

CAVEATS
     Historically, this function has been described as returning a pixel-width, but was imple-
     mented to return the width in model-space units, rounded to integers. GLUT never resolved
     this, and freeglut duplicated the confusion. OpenGLUT has decided to stay in model-space and
     to return the unrounded floating point value. An unreleased GLUT 3.8 was supposed to include
     glutStrokeWidthf() and glutStrokeLengthf() (note the *f suffixes), but that is not in wide
     use.

TODO
     Determine if any glyphs are either wider than this function or if they render outside of the
     bounding box given by  (0,-descent)   by  (width,height-descent)  .
