In C++, type punning with a union is not allowed. It will result in
compiler defined behavior at best, and undefined behavior at worst.
Specifically, if QRgba64 is passed to a function by value, the different
members of a struct might be passed in separate registers. This means
that any write to the quint64 might not blank out the values of the
struct whenever the compiler looses track with TBAA.

Just like from RGB32 to RGB30 we must also repremultiply when converting
from RGB64 because the alpha channel loses more precision than the other

Since this is not approximated accurately in the simple blending

engine supports higher accuracy, the simple blending routines for RGB30

If a cosmetic polyline contained a 1-pixel segment, the next segment
would be drawn with wrong starting point.
The original fix for QTBUG-26156 had some unwanted side effects
(QTBUG-31579 and now QTBUG-42398). It tried to skip start-point update
if stroke() did not actually draw anything (because the segment was
too small). However, to determine that, it tested for a change in
lastPixel. But that was not failsafe; in some cases (1-pixel segment),
lastPixel could be unchanged even though the segment had been
drawn. With this change, we instead test directly whether stroke()
skipped the segment or not.

However the default in QBitmap is (unfortunately) QBrush(color0), rather

I suppose the real issue is that lastBrush is default-constructed in
QRasterPaintEngine, rather than starting with the brush from QPainter,
which is QBrush(color0) for the case of the bitmap. But no reason to
special case NoBrush here anyway.
