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