Well "fairly  garbled" might be a bit strong, I suspect. 

The buttons inside groups are being drawn by Windows as if
WS_EX_TRANSPARENT was set on them. This means that the area they
occupied is drawn as a solid black background then the button is correctly
drawn on top of that, thus giving it a solid black border.

The nested group control has two issues. The caption is the wrong font size,
and the group border is being drawn underneath the caption.

I've tried all sorts of things to get around these but failed so far. So
I'll keep trying but any hints are most welcome.

The third issue is that a disabled scroll bar has being rendered with the
same color as its background, thus making it disappear (except for the
up/down arrows). This one I've found a fix for.
