4 | * TODO: |
5 | * |
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. |
