Title: TexturePacker optimized by using BitmapData to implement _mask

Optimization for TexturePacker.

Rewrite masking functionality using:
protected var _mask :BitmapData;
BitmapData.hitTest(...);
BitmapData.fillRect(...);
BitmapData.getPixel32(...);

Significant performance improvement noticeable with large texture atlases.
