I'm not saying it does, but if we are using a string font to be consistent with PIXI.Text, then it should support the same things. I would prefer to have the params passed separately as arguments or in the style object.

I think something like `PIXI.BitmapText = function(text, font, style)` where `font` is the string font name, and `style` is an object with size and other stuff would be best.
