The current AxisScale will not support unevenly spaced tick 
marks.  Logarithmic axes are on my list of things to do, but
finding the time is not even on my radar screen.  It will involve
changes to ScalarMap and Display (for new display types). 

Anyone else who wants to tackle this is welcome to.
