This is an excellent class! Thank you for sharing!

I fount a small bug, it throwed me a BitmapData argument error, when it occured to the bitmapWith or bitmapHeight property to be less than 1.
I worked it around with a pach at line 129 and 130:
from:
bitmapWidth = (Math.max(tlX, brX) + distance)*2;
bitmapHeight = Math.max(tlY, brY)*2;
to:
bitmapWidth = Math.ceil((Math.max(tlX, brX) + distance)*2);
bitmapHeight = Math.ceil(Math.max(tlY, brY)*2);

I hope this helps others..
Thank you!

Sorry – you can’t extend an existing sprite with this class. Think of it more like a container sprite – i.e. you should create an instance of your sprite then add it as a child to an instance of MotionBlurSprite. I’ll update the notes.
