Attached is Controls.zip, an improved version of the button and slider
machinery I posted yesterday.
Two significant changes:
1) Instead of horizontal sliders and vertical sliders, there is just one
kind of slider, and it can point in any direction, specified by "axis". The
demo has a vertical slider and a slider at an angle.
2) Instead of a 100 by 100 coordinate system with (0,0) in the lower left
corner, I reverted to standard Visual conventions. The origin is at the
center of the screen, and you can use any units you like to set up buttons
and sliders. For buttons, pos is at the center (like box) and for sliders
pos is at one end (like cylinder).
