Log Message:
-----------
Added some logic to Axes.bar that will preconvert unitized data before creating 
the rectangular Patch since not all unitized data can be subtracted with a floating
point number (ie. 'left - width') this is especially true with 'time' (time - time = duration).
This problem can be seen when passing in a floating-point number for the width, which
in-turn should be interpreted to be a number in the units for the axis.  This was not
being done, and now is.  There is probably a better way to handle this.
