Review request for Dolphin.


Description
-------

This is a follow-up to https://git.reviewboard.kde.org/r/108858/ . It has been brought to my attention the painting code I wrote was still wrong: when you mouse over items, the transition between the normal and hover images is not as smooth as it should be. Especially at the end, one has the feeling of a "bump".

I did quite a bit of debugging on that bug and wrote the result of my research in a huge comment. It may be too big, I am happy to remove it. I am probably going to blog about this anyway, since the hunt for that bug was interesting.

Moved the mouse over normal and hidden items, transition is smooth.
