Given what it sounds like your content is, I might consider putting the whole canvas on a single or small set of tiled layers (they can be unbounded in size).


Oh. I had thought making each individual part its own CALayer was most appropriate. I intend for each part to change its appearance to reflect selection, hover, etc, as well as be draggable, rotatable, etc. Animating these these changes seems to dictate making each its own layer.

Now, I'm not really sure how to animate something I'm drawing directly (for example, when you're hovering over a part, I would like it's "significant contour" to pulsate, or something like that).
