Lime Progressbar#
Horizontal	Vertical
rectangles	radial

Let's see if we can reuse two of the thumb images for the trough, then all we require are internal parts to form the horizontal and vertical progress sliders. The horizontal slider used rectangles and the vertical one used points for radial gradients, so a comparison can be made.

progressbar

Standard gradient on vertical to create 90° gradient to normal
