 NAME     
 |  |  |  | stringsize, stringwidth, stringnwidth, runestringsize, runestringwidth,
    runestringnwidth – graphical size of strings 
 | 
 SYNOPSIS     
 |  |  |  | #include <u.h> #include <libc.h>
 #include <draw.h>
 Point stringsize(Font *f, char *s)
 int    stringwidth(Font *f, char *s)
 int    stringnwidth(Font *f, char *s, int n)
 Point runestringsize(Font *f, Rune *s)
 int    runestringwidth(Font *f, Rune *s)
 int    runestringnwidth(Font *f, Rune *s, int n)

 DESCRIPTION     
 |  |  |  | These routines compute the geometrical extent of character strings
    when drawn on the display. The most straightforward, stringsize,
    returns a Point representing the vector from upper left to lower
    right of the NUL-terminated string s drawn in font f. Stringwidth
    returns just the x component. Stringnwidth returns the width of
    the first n
    characters of s. 
    
    
    The routines beginning with rune are analogous, but accept an
    array of runes rather than UTF-encoded bytes.

 DIAGNOSTICS     
 |  |  |  | Because strings are loaded dynamically, these routines may generate
    I/O to the server and produce calls to the graphics error function.
