[bug report] frame shadow skin

[swallowsoul]

There are some frames which are still displaying BUI shadows, even with them disabled.
Here are the ones I found, via /fstack:

bui_frames={
	GroupLootHistoryFrame.ResizeButton
	MirrorTimerContainer
	VehicleLeaveButton
}

I think there are some more, but I forgot to pick them up. I'll update this if I found them again...

Had time today to go through those. I think I got them all.
Let me know if there are even more. Thank you

I found some newer ones... I think almost all aura frames are displaying some sort of hardcoded shadows even with them disabled in BUI. And the VehicleLeaveButton is still displaying them too.

Welp, there were still lots of them :)
I think I got them all now
