trouble with shapes? and rotate a gradient?

[jerry anning]

I dug my shakes and ladders game out of mothballs, and I wanted to use
shapes, in particular curve_to to make the curved snaky forms. I am using
r925 on windows xp and the shape seems to just silently not draw, with no
errors or warnings in the shoes console.  here is a snippet:

Shoes.app(:height => 640, :width => 640) do
  background orange
  stroke green
  strokewidth 5
  fill yellow
  shape :left => 30, :top => 30 do
    line_to 50, 30
    curve_to 100, 100, 10, 20, 100, 50
    line_to 20, 100
    line_to 30, 30
  end
end

Is it a shoes issue, a windows issue, has the api changed, or am i just
doing it wrong?

Also, are there plans to make it possible to rotate a gradient? This would
be useful, for instance, to show direction of lighting.
