Not really. The ability to "know what is a wing and what is a beak" requires some rudimentary edge detection and that the colored area not change from frame to frame in increments large enough to cause the program to lose the color in question at a given X/Y coordinate. Yes, it can be done. But even the simple bird flying animation would have problems with sudden movements (the wings appearing below the bird on the bottom of the stroke). I talked with Leo about this several years ago, basically suggesting what you did. He wasn't sure it could be done. What is clear is that it can't be done reliably, and TAS is for naive, inexperienced users. What is perfectly acceptables for professionals at TBS may not be acceptable for such users. On the other hand, the demo on CC managed to missed coloring one part of the wing for one frame. A "check coloring" feature for detecting such would be nice. Wouldn't be hard, either - except for dealing with things colored in the background color. [NB - I don't own TAS, so this may be there.]
