Constructor Detail
Creates a Gsk::RenderNode
that draws a conic gradient.
The conic gradient starts around @center in the direction of @rotation. A rotation of 0 means that the gradient points up. Color stops are then added clockwise.

Instance Method Detail
Retrieves the angle for the gradient in radians, normalized in [0, 2 * PI].
The angle is starting at the top and going clockwise, as expressed in the css specification:
angle = 90 - gsk_conic_gradient_node_get_rotation()
