Optimized (fast) Orthogonal Tilemap Layer
Cocos2D's tilemap layer does not limit drawing of tiles to what is on screen, which causes large tilemaps (eg maps 100x100 or larger) to suffer from a severe performance penalty. An optimized orthogonal Tilemap layer would only render the tiles that are (partially) inside the view, which would make even huge tilemaps as fast as a view-sized tilemap. Memory usage should also decrease significantly for large tilemaps.
I haven't seen this HKTMXTileMap yet but it seems to be similar what I have in mind. Although with Mac and Retina support of course.
is this the same kinda thing as http://www.cocos2d-iphone.org/forum/topic/17945?
if that could fix it and add tile animation that would be nice :)
