[DM-dev] rendering of rooms works.

[Stephan B. <st...@wa...>]

Here's a sample:

    DungeonElement top( "dungeon" );
    DungeonElement *de = new Room();
    de->setName( "roomX" );
    de->move( 3, 5 );
    top.add( room );
    de = new Room( 7,3, "wide room" );
    de->move( 17,4 );
    top.add( de );
    de = new Room( 5,8, "tall room" );
    de->move( 10,1 );
    top.add( de );
    DMGrid grid( 20, 20 );
    CERR << "after rendering:" << endl;
    top.renderTo( grid );
    grid.dump();

(Doors will be added later.)

Note how all of that is done through the generic DungeonElement API, and not 
Room's specific API. Basically, anything which goes in a Dungeon in a 
DungeonElement, and has lots of behaviour in common (moving, resizing, etc.), 
though each may implement that completely differently.

This code draws us with the following map:

00000000000000000000
00000000001111100000
00000000001000100000
00000000001000100000
00000000001000100111
00011111001000100100
00010001001000100111
00010001001000100000
00010001001111100000
00011111000000000000
00000000000000000000
00000000000000000000
00000000000000000000
00000000000000000000
00000000000000000000
00000000000000000000
00000000000000000000
00000000000000000000
00000000000000000000
00000000000000000000

(Sorry for the ugly output - I haven't yet got the char/int mapping support 
done.)

DMGrid provides a resizable grid. If it's resized, though, all renderings are 
nuked. Any attempts to write outside it's boundaries are ignored. You'll see 
that in the above map, the "wide room" overflows off the side.

The rendering code is spread out: the recursive functionality is in 
DungeonElement. The actual drawing of data is left to the subclasses. Room 
draws nothing, but it's 4 children each draw themselves.

See ya!
