Not sure what the best way is, maybe setting the z so that it's right on the camera's near clipping plane?

This is examples/gridplot/gridplot.py

   I see that the image graphics are moved towards the camera, and it looks that if I add another image to the same subplot, it is moved even further:

   >> figure[0, 0].graphics[0].world_object.local.z
   1.0
   >> figure[0, 0].graphics[1].world_object.local.z
   2.0

   Is this correct? It also happens to lines, I think. However, I cannot find where this happens, could you help me point to the point in code where this offset is calculated?

   Some more general thoughts:

   • For 2D viewing, using the z-offset is fine. For 3D this is still fine for 2D data (i.e. stacking images this way feels fine to me, but as soon as someone draws a 3D scatter, you really don't want to touch the offset, because that dimension probably means something.
   • Idea: don't set the offset except for images. These are set at -1, and earlier-added images are pushed backwards. Then use depth_compare = "<=" for the ruler to it's on top of everything rendered at z=0.
