Simon Tatham 64e114cce1 draw_polygon() and draw_circle() have always had a portability 
constraint: because some front ends interpret `draw filled shape' to
mean `including its boundary' while others interpret it to mean `not
including its boundary' (and X seems to vacillate between the two
opinions as it moves around the shape!), you MUST NOT draw a filled
shape only. You can fill in one colour and outline in another, you
can fill or outline in the same colour, or you can just outline, but
just filling is a no-no.

This leads to a _lot_ of double calls to these functions, so I've
changed the interface. draw_circle() and draw_polygon() now each
take two colour arguments, a fill colour (which can be -1 for none)
and an outline colour (which must be valid). This should simplify
code in the game back ends, while also reducing the possibility for
coding error.

/*
* 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.
