how to get pixel coordinates of vpython.label object?

[Horst JENS]

Is there a method to get the x,y pixel coordinates of a vpython 3d label object ?

less important, is there a method to get the size (width, height) of a vpython label object ?

details:

I have an 3d vector and use it as a the pos argument for an vpython label object. The label is displayed, i want to know the xy pixel coordinate of the label (distance from the lower left screen corner) and also the size of the label object in pixel.

I can't think of a way to determine the current width and height of a label, but scene.pixel_to_world tells you how big a pixel is in world coordinates. Also, scene.range gives you in world coordinates half the shorter of scene.width/2 and scene.height/2.
