NAME
     getdescender - returns the character characteristics

C SPECIFICATION
     long getdescender();

PARAMETERS
     none

FUNCTION RETURN VALUE
     The returned value of this function is the length (in pixels) of the
     longest descender in the current font.

DESCRIPTION
     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.
