So - there is a bug in either how we import PNGs for toolbar rendering, or in
how we composite them :-)

eg. if you take Industrial's lc_undo.png - and take a shot of the toolbar
showing it (in 24bit color etc.) - you notice that the pixel values of eg. the
lower block part in the arrow head are different values - as much as 10%
different in R & G [ but blue tends to  be more correct (odd) ].

I guess this is some bug / rounding error / something in the VCL png loading
code. The pixels in question have 100% opacity, so unlikely to be an alpha issue
but ...

I attach a photograph of the problem [ most noticable when you start comparing
the insensitivity code ;-]
