Implement shape for InfoElement

Description

Implementing the shape for the infoelement to not react on events on the bounding rect, because the bounding rect is the complete plot

Previously when right click just on the plot, it was impossible to select the plot, because the infoelement is always on top and fills the complete datarect.
