wx.ScrolledWindow uses a scroll unit value which is the number of pixels 
the window will be scrolled with each step, (a.k.a. the scroll rate.) 
Because of this the virtual size of the window will always be a multiple 
of this unit size.  So if the size needed by the grid is not an exact 
multiple of the unit size then it will actually tell the scrollbars that 
it needs something like width + rate - (width % rate) pixels.  To size 
the columns such that no scrollbar appears then it needs to be the 
multiple of the scroll rate that is <= width.
