Summary: Zero Height Gradient Rectangle Brush Exception

Initial Comment:
There is an unhandled exception when creating a zero height gradient rectangle brush.

How to Reproduce:
Create a bar plot with the bars filled in vertical gradient mode (color changes along the y-axis).  Manually resize the containing window until one of the bars becomes zero pixels high (with a non-zero data point).  As soon as this happens, the application will crash with an unhandled exception.

Recommended Fix:
Before painting the bar for a data point, check for zero height.  If zero height, maybe draw a single pixel line at that point, but don't bother creating the rectangle or gradient fill brush.
