You set hints to the window manager how big an increment (character size) is 
in x and y directions.  You also tell it the minimum size (i.e. the size of 
the scrollbars, fringes, menu and toolbar) of your window.  That way the WM 
can calculate the character increment and display that when the window is resized.

That is true.
