It comes from here:
http://www.w3schools.com/jquerymobile/jquerymobile_form_sliders.asp
Here's a prototype using the new data structure [draw] commands I mentioned. (Attached)
to the [struct] to store the slider value. Then I could create lots of sliders with different values. It's also possible to add fields to control the scaling, rotation, colors, etc.
I probably need some extra event types to specify the beginning and end of the drag event* Obviously adding text is trickier. CSS basically exists to gracefully handle text-flow* You can right-click the scalar and choose "Properties" to change the fields.
