/**
*
* SWT's {@link SashForm} is moronic. There is no way to set the colour of just
* the sashes... calling {@link #setBackground(Color)} results in setting the
* background colour of the entire form area.
*
*
* This class has to use nasty hacks to give us access to the superclass fields
* that we need to modify. It's a toss up between this and completely
* reimplementing {@link SashForm}.
