Touch controls for moving point only on x axis #68

Closed KatieWoe closed 5 years ago

When moving the value point, it only moves when dragged along the x axis. This did not present much problem, but did in graphing quadratics, see https://github.com/phetsims/graphing-quadratics/issues/117. Specific code change was made to that sim, and may be worth examining here.

I don't think that in this simulations that the dot moves only in the x axis is a problem, and also in the beginning the arrows show to the user that the dot moves if the drag movements is in the x axis. I think that @arnabp can review the code that Chris did for Graphing-quadratics and see if can improve the performance in blackbody, but I don't see it as urgent.

This was discussed in the last pixel polish meeting, and decided that the point should be draggable only on the x axis, closing.
