+/* 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.
+ - For textedit, similar rules hold, but they are less strict.
+ XXX more?
