* windows.c: Windows front end for my puzzle collection.
*
* TODO:
*
* - Figure out what to do if a puzzle requests a size bigger than
* the screen will take. In principle we could put scrollbars in
* the window, although that would be pretty horrid. Another
* option is to detect in advance that this will be a problem -
* we can probably tell this using midend_size() before actually
* generating the puzzle - and simply refuse to do it.
