Removed TextDesigner offset flooring

I don't know if this is to help pixel alignment or something, but I don't run my game at a scale that is the same as the resolution, and with the varied devices that are out there I'm not sure many does? With a lower scale that flooring can move the text around big time, which it did for me :)
