/* Stdwin module */

/* Stdwin itself is a module, not a separate object type.
   Object types defined here:
	wp: a window
	dp: a drawing structure (only one can exist at a time)
	mp: a menu
	tp: a textedit block
*/

/* Rules for translating C stdwin function calls into Python stwin:
   - All names drop their initial letter 'w'
   - Functions with a window as first parameter are methods of window objects
   - There is no equivalent for wclose(); just delete the window object
     (all references to it!)  (XXX maybe this is a bad idea)
   - w.begindrawing() returns a drawing object
   - There is no equivalent for wenddrawing(win); just delete the drawing
      object (all references to it!)  (XXX maybe this is a bad idea)
   - Functions that may only be used inside wbegindrawing / wendddrawing
     are methods of the drawing object; this includes the text measurement
     functions (which however have doubles as module functions).
   - Methods of the drawing object drop an initial 'draw' from their name
     if they have it, e.g., wdrawline() --> d.line()
   - The obvious type conversions: int --> intobject; string --> stringobject
   - A text parameter followed by a length parameter is only a text (string)
     parameter in Python
   - A point or other pair of horizontal and vertical coordinates is always
     a pair of integers in Python
   - Two points forming a rectangle or endpoints of a line segment are a
     pair of points in Python
   - The arguments to d.elarc() are three points.
   - The functions wgetclip() and wsetclip() are translated into
     stdwin.getcutbuffer() and stdwin.setcutbuffer(); 'clip' is really
     a bad word for what these functions do (clipping has a different
     meaning in the drawing world), while cutbuffer is standard X jargon.
     XXX This must change again in the light of changes to stdwin!
   - For textedit, similar rules hold, but they are less strict.
   XXX more?
