File "fxlayers.xml"

Used to store information about overlays used in the stages. Unlike other Isaac XMLs, the file does not have one overarching element containing everything inside, instead being seperated into the elements fxLayers, fxRays, and fxParams.

Resource-Folder: Placing this file in a resource folder of a mod will override the original.

Content-Folder: Using this file in a content folder of a mod is not tested yet.
