Any layer with one or more tiles gives bad perfomance, Layer without tiles, good

[Demkamen]

Any layer with one or more tiles gives bad performance, Layer without tiles, good for performance. 3 or more layers(with tiles) gives bad performance for flash in full screen in browsers.  So layers with simply actors better for performance. But I believe that the tiles should not affect performance!

We can't make layers with tiles perform the same as layers without, but we can probably allow the scene to have different rendering options, allowing some of the more expensive tile-related operations faster at the expense of memory.

letmethink made some changes in his own branch of the engine, some of which are mentioned in the jittering thread. If we can provide advanced rendering options to allow full tile layers to be rendered once and retained in memory, that might help performance here and help with the jitter there.
