Hi,

I did try owner-draw, but it isn't good enough for what I want to do, 
because I actually need to draw to the left of the disclosure controls.  
On Windows, the disclosure controls are always up against the left side of 
the tree control, and there's no clean way to move them over within the 
tree control itself, as far as I can tell (even in native Win32 code).  
That's why I think I need to draw to the left, outside the tree control, 
and keep track of the tree's scroll position in order to know what to draw.

Thanks,

nj
