/** Sets the brush colour.
The brush is used for filling shapes and the background of text boxes. The 
brush has colour, style, pattern and pattern origin parameters.
If no brush colour has been set, it defaults to white. However the default 
brush style is null, so when drawing to a window the default appears to be 
the window's background colour.

@param aColor The logical colour for the brush.
