Is the problem that the bounding box does not match the size of the  
plot? That the plots "bleed" over onto subsequent pages? Do you have  
a example that demonstrates the undesired behavior?

I was not aware of this convention, but I'll see if that is possible.

Is this just for the 3D labels? I'm not sure why 2D labels would be  
differently sized than 3D labels.

Do you mean clipping the text at the edge of the plotting area?
