/*
* Mac OS X / Cocoa front end to puzzles.
*
* Still to do:
*
* - I'd like to be able to call up context help for a specific
* game at a time.
*
* Mac interface issues that possibly could be done better:
*
* - is there a better approach to frontend_default_colour?
*
* - do we need any more options in the Window menu?
*
* - can / should we be doing anything with the titles of the
* configuration boxes?
*
* - not sure what I should be doing about default window
* placement. Centring new windows is a bit feeble, but what's
* better? Is there a standard way to tell the OS "here's the
* _size_ of window I want, now use your best judgment about the
* initial position"?
* + there's a standard _policy_ on window placement, given in
* the HI guidelines. Have to implement it ourselves though,
* bah.
*
* - a brief frob of the Mac numeric keypad suggests that it
* generates numbers no matter what you do. I wonder if I should
* try to figure out a way of detecting keypad codes so I can
* implement UP_LEFT and friends. Alternatively, perhaps I
* should simply assign the number keys to UP_LEFT et al?
* They're not in use for anything else right now.
*
* - see if we can do anything to one-button-ise the multi-button
* dependent puzzle UIs:
* - Pattern is a _little_ unwieldy but not too bad (since
* generally you never need the middle button unless you've
* made a mistake, so it's just click versus command-click).
* - Net is utterly vile; having normal click be one rotate and
* command-click be the other introduces a horrid asymmetry,
* and yet requiring a shift key for _each_ click would be
* even worse because rotation feels as if it ought to be the
* default action. I fear this is why the Flash Net had the
* UI it did...
* + I've tried out an alternative dragging interface for
* Net; it might work nicely for stylus-based platforms
* where you have better hand/eye feedback for the thing
* you're clicking on, but it's rather unwieldy on the
* Mac. I fear even shift-clicking is better than that.
*
* - Should we _return_ to a game configuration sheet once an
* error is reported by midend_set_config, to allow the user to
* correct the one faulty input and keep the other five OK ones?
* The Apple `one sheet at a time' restriction would require me
* to do this by closing the config sheet, opening the alert
* sheet, and then reopening the config sheet when the alert is
* closed; and the human interface types, who presumably
* invented the one-sheet-at-a-time rule for good reasons, might
* look with disfavour on me trying to get round them to fake a
* nested sheet. On the other hand I think there are good
* practical reasons for wanting it that way. Uncertain.
*
* - User feedback dislikes nothing happening when you start the
* app; they suggest a finder-like window containing an icon for
* each puzzle type, enabling you to start one easily. Needs
* thought.
*
* Grotty implementation details that could probably be improved:
*
* - I am _utterly_ unconvinced that NSImageView was the right way
* to go about having a window with a reliable backing store! It
* just doesn't feel right; NSImageView is a _control_. Is there
* a simpler way?
*
* - Resizing is currently very bad; rather than bother to work
* out how to resize the NSImageView, I just splatter and
* recreate it.
