/*
* 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.
