Randomly Mirrored Corpses doesn't work well with rotations

Tested in the latest master artifact (Win-64).

Simply put, if the Randomly Mirrored Corpses effect is applied to something with rotations, the thing's rotation will look weird.

In this case, I replaced one of the gibbed-player decorations with a chair, which is affected:

Options to fix this would be to not apply the effect to things modified by DeHackEd, or to perform a thorough analysis to determine if the effect should be applied, which I think would be optimal. However, in case the latter is too complex, I propose something different: flipping the sprite just like we do currently, but using the opposite rotation, i.e. (8 - rot) & 7. What do you think?

How would this look like in the video?

With this specific set of sprites, it would look pretty much identical to how it looks in the video.

Here's a better example, halfway through this video I toggle a setting to flip the sprite and use the opposite rotation (I already have that system in place for use with a feature to "flip levels"):
