For image-orientation property, we use methods of nsStyleImageOrientation struct to create/set its computed value. Adding these binding functions could let us reuse these methods for transferring computed values from Servo side to Gecko. The actual changes for the calling these binding functions to do the glue things for Stylo is in a separate following patch, which should be pure Servo changes.
