A new question/issue - on line 314, what happens if the case is both
quadrant rotated and extra-alpha'd? Either of those will get us into that
code block, but also both of them could be true at the same time in which
case it looks like you forego the retreival of the EA mask...?
In this case a 1x1 mask with EA prepared in advance by
XRCompositionManager will be used, returned by
xrMgr.getExtraAlphaMask().
I think I had that backwards. I was referring to the other case which
does not call xrMgr.getExtraAlphaMask():
312 // For quadrant-transformed blits geometry is not
stored inside the mask
313 // therefore we can use a repeating 1x1 mask for
applying extra alpha.
314 int maskPicture = isQuadrantRotated ?
xrMgr.getExtraAlphaMask()
315 : mask.prepareBlitMask(x11sdDst, maskTX,
width, height);
In the "mask.prepareBlitMask" case I don't see where extra alpha is
processed, but perhaps I am missing something and it is already
registered in some data structure somewhere?
