Grant Skinner mentions the dreaded wrapping spaces bug. This is where dynamic textfields will wrap spaces on the end of a line to the
front of the next line, creating an uneven left margin. One solution
is to slightly increment the textfield’s width after setting the text. As a textfield prototype:

	TextField.prototype.unwrapSpaces = function() {
		this._width = this._width + 0.01;
	}
