Thanks for the answer , very helpful.
Can you tell me when was this ? I mean was it the latest version of Air ?
All in all i found these concerning:
In practice, you may need some tweaking (not code, but graphics). For example:
* A movieclip i had slightly rotated (5 degrees) showed some noise in its texture.
* Or a dragging object moved anoyingly slow when going through another complex object.
* Or things that were scaled down showed very pixelated (despite being vector).
* And you may exprience FPS dropdowns on small devices if you have too many objects/too complex objects.
Sounds like the Air transforms vectors into bitmaps, this is what it has problems with rotated or resized movie clips.
Or at least I speculate.
