// todo: remember the size of textareas?
// todo: resize textarea to max size (that fits browser window). Loop adding rows until the bottom coordinates are too big.
// todo: make it work with dynamically updated pages such as Gmail
// todo: doesn't work for textareas that are sized using width and height, only cols and rows.


// Update (2005/09/09):
// Included Mark Pilgrim's fix for DeerPark:
// can't call scrollInView on an XPCNativeWrapper, must check for scrollIntoView function and call .wrappedJSObject.scrollIntoView (yuck)
