z-fighting for two cameras that have same plane distance from reference point

[pd-nisse]

Describe the bug
I have two cameras with same focal lengths

To Reproduce
Steps to reproduce the behavior:
Add two pinhole cameras to the same reference point with the following intrinsics:
Camera 1:

width=1920,
height=1080,
fx=630.0,
fy=630.0,
cx=960.0,
cy=540.0,

Camera 2:

width=1920,
height=1080,
fx=500.0,
fy=500.0,
cx=960.0,
cy=540.0,

Expected behavior
I'm actually not sure what to expect when they're overlapping. But the z fighting is definitely not the best solution. Maybe pick the smaller area to be slightly in front of the larger area?

Screenshots
Ignore the third (closest) camera.

Not a big issue, but an imperfection in a certain scneario

This is now fixed as part of the 0.32 release, as a byproduct of some rendering improvements for the new GridMap archetype 😁
