TTrackBar is a windows common control. We need to correct win32
widgetset code to let it draw transparently on parent controls if themes
are enabled. Feel free to create a patch which solves this problem.
TStringGrid is a control which LCL draws itself. We need to use more
themes painting to make it look more native. This can be done later.
And, btw, color is not clWhite - theme services are using bitmaps to
draw control surfaces. If you change theme to another it can look as
Blue or Black or as any other color.
