This class allows to animate OpenGL drawing operations in SketchUp. You can see examples in this video.

• AE::Animation.draw(view)
  Call this in the draw method of your SketchUp tool.

• AE::Animation.new(view, drawing_operations)
  with view as the current Sketchup::View of your tool and drawing_operations as an Array in which each drawing operation is represented as an array of the method's name (as Symbol) and its arguments

• <AE::Animation>.animate(properties)
  with properties as a Hash containing :duration [Numeric]
  :repeat [Numeric] how often to repeat this animation within duration
  :easing [Symbol] one of :linear, :quad, :quad2, :cubic, :cubic2, :quartic, :quartic2, :quintic, :quintic2, :swing, :gauss, :elastic, :bounce
  The following properties can also have a Hash assigned with a start value :from, end value :to and optionally an easing.
  :color [String, Sketchup::Color]
  :alpha [Fixnum<0..255>, Float<0.0..1.0>]
  :line_width [Fixnum]
  :transformation [Geom::Transformation]
  :translation [Geom::Vector3d]
  :scaling [Array] with arguments of SketchUp's Geom::Transformation.scaling method
  :rotation [Array] with arguments of SketchUp's Geom::Transformation.rotation method

• <AE::Animation>.wait(duration)
  with duration as a Number of how many seconds to wait.

Animation.new(view, [
  [:draw, GL_POLYGON, circle],
]).
animate({
  :color => {
    :from => "yellow",
    :to => "orange",
    :easing => :gauss
  },
  :scaling => { :from => [p, 0], :to => [p, 2] },
  :alpha => { :from => 0.0, :to => 1.0, :easing => :gauss },
  :duration => 2
})
