--- Comment #4 from Victor Wren <[email protected]> ---
To clarify, the GUI control corresponds to the angle in the numerical selector
box, but neither of them corresponds to the angle of the shadow in the preview 
on-screen.  So the number agrees with the GUI spinner control (i.e. 0 is
vertical, 90 is to the right, 180 is at the bottom and -90 is to the left), but
the controls don't agree with what is actually on the layer.

i.e. "0" puts the spinner dot at the top, the light source at the right, the
shadow at the left

"90" puts the spinner at the right, the light source at the top, the shadow at
the bottom,

"180" puts the spinner at the bottom, the light source at the left, the shadow
to the right,

"-90" puts the spinner at the left, the light source at the bottom, the shadow
at the top.

As the number increases, suggesting a clockwise rotation of the light source,
the spinner moves clockwise as expected, but the apparent light source on the
preview rotates counter-clockwise.

This is probably a simple subtraction error somewhere.
