undocumented skew method on images

[passenger94]

Shoes.app do
    img = image "#{DIR}/static/man-ele-image.png", left: 50, top: 50
    img.skew 7.5, 9.5  # accepts 1 or 2 args
end

also rotate and scale

for shapes and images works also like this : (no methods on shapes)

Shoes.app do
   skew 12.25
   image "#{DIR}/static/man-ele-image.png", left: 50, top: 50
   rect 50,50,86,39
end

skew is mentioned for shapes in transform method but not documented and scale is also not documented for shapes

So many undocumented features. The manual is going to get bigger and bigger.
