--- Comment #2 from Simon Fraser (smfr) <simon.fraser at apple.com> ---
Crossfade draws with:

    context.beginTransparencyLayer(1);

    drawCrossfadeSubimage(context, m_fromImage.get(), CompositeSourceOver, 1 - m_percentage, m_crossfadeSize);
    drawCrossfadeSubimage(context, m_toImage.get(), CompositePlusLighter, m_percentage, m_crossfadeSize);

    context.endTransparencyLayer();

which I would expect to work, unless it fails because of non-linear gamma?

It works correctly if we always go down the "useTransparencyLayer" code path.
