Sets the general layering strata of the frame. Where frame level provides fine control over the layering of frames, frame strata provides a coarser level of layering control: frames in a higher strata always appear "in front of" frames in lower strata regardless of frame level.
Signature:
Code
Frame:SetFrameStrata("strata")
Arguments:
strata - Token identifying the strata in which the frame should be layered (string, frameStrata)
