This adds drawing the wave line (typically used to underline the wrongly spelled words) with bezier curves. Previously the wave lines were drawn with drawing pixels, which didn't look that good, especially on HiDPI display, so the looks of wave lines now is therefor much better. The creation of the wave line as a polygon has been added to the basegfx module, so it can be reused if needed. In addition, everytime we draw the waveline, we have to enable antialiasing, to have a much better quality of the curves. By default the antialiasing is disabled for some reason. This also adds ScopedStates.hxx file which currently includes ScopedAntialiasing, which sets the antialiasing to a certain state for the time the object is in scope, and then sets it back to the original state.
