maskBeforesafeFlipY: boolean = falseFlag that indicates the applied filter is Y-symmetric.
MaskFilter will optimize rendering by not flipping the screen backdrop before passing it to the blend filter for Y-symmetric filters.
A filter is Y-symmetric if giving it an inverted input and then inverting the output is equivalent to giving it an upright input.
