I was expecting/wanting mirror() to simply flip the image over the indicated axes.
Instead, I am seeing it do a weird effect where the image isn’t just flipped, but turned into some sort of symmetricalized version of itself.
So I have an image like this:
that during setup I load and set up like this:
And instead of a simple flip, it ends up transmogrified into this (ignore the rotation and green):
Is this a bug in .mirror(), or have I just not found some bug in my own code?
Or is it supposed to do this, and I need to achieve a simple flip in some other (?) way?
