Symmetry bug(?) with spatially varying sources

[ataras2]

First of all I want to say that I think this is a great package, thank you so much for developing and maintaining it!

I'm trying to simulate a larger device with x+y mirror symmetry. The input field is also symmetric but not spatially uniform.
A minimal example that recreates my issues is here: minimal_source_bug.py

I place a GaussianPlaneSource in the center of my volume when running with symmetry on. After running the simulation, the source is still placed at the center of the quadrant when I expect it to be at the bottom left:

Is there something I'm missing here? Have also tried moving the source but it doesn't seem to move.

@ataras2 thanks for reporting this, symmetry is a new feature that we have not tested and documented well yet. I will make a PR to fix the bug soon :)

Confirmed. I tested this feature (originally) with ModeSource & UniformPlaneSource. ModeSources get oriented appropriately, Gaussians weren't tested since uniform sources are invariant to a placement shift.
