Fwd: [Bug 135165] Rotating an imported NEF (Nikon RAW) image 180° produces empty area, undoing produces empty image

[Boudewijn Rempt]

Just a question related to the solution to this bug -- perhaps someone on the 
list knows the answer...

* Why do we have to open the source iterator writable?
-        KisHLineIteratorPixel srcIt = src->createHLineIterator(r.x(), y, 
r.width(), false);
+        KisHLineIteratorPixel srcIt = src->createHLineIterator(r.x(), y, 
r.width(), true);

* Why do we try to set the alpha channel of the source paint device?

data = srcIt.rawData();
// XXX: Should set alpha = alpha*(1-selectedness)
cs->setAlpha(data, 0, 1);

Cyrille, Bart and me, we're all baffled as bathroom geysers, although pretty 
elated that this bug has been solved in time for 1.6.
