DESCRIPTION    [Toc]    [Back]

     getdescender returns the maximum distance (in pixels) between the
     baseline of a character and the bottom of the bitmap for that character.

     Each character in a font is defined using a bitmap	that is	displayed
     relative to the current character position.  Vertical placement of	each
     character is done using the current character position as the baseline or
     the line on the page.  The	portion	of a character that extends below the
     baseline is called	a descender.  The lowercase characters g and p
     typically have descenders.
