Background image support of ExplorerTreeView

[TiKu]

I'm working on Vista compatibility of ExplorerTreeView 1.x and 2.x. While most things are done already, the background image support drives me nuts.
Up to Windows XP/2003, the code is a horrible bunch of hacks, but it works well enough to make this feature somewhat usable. But the code doesn't work on Vista and so far all my attempts to find another working implementation have failed.
The more time I spend for ExplorerTreeView background image support, the more I tend to say it is a waste of time. I'm really thinking about dropping BkImage support, but before doing so, I'd like to hear your opinions, so I've started a vote.
