[DUG] png buttons, actionbars

[Alister Christie]

I've been using PNGComponents (http://thany.org) for awhile now and 
found them pretty good.  I've never actually used a TActionToolBar (I 
probably should investigate more) but can verify the problem your 
having.  It will probably relate to the TActionToolBar trying to draw 
the shadows and not having support for the alpha channel - I suspect 
fixing this would be challenging, I've had a quick look at the source 
but can't find the code that specifically draws the shadow - however 
many of the related methods are virtual so you maybe able to write a 
descendant with better PNG support.  I unfortunately have to disappear 
onsite with a client (otherwise I'd try to track it down).
