Fixed incorrect XmRenderTableToProp() behavior appeared in RendToProp test. The function wrote -1 is background or foreground pixel value is XmAS_IS, but XmAS_IS has the same value as blue color pixel (255),  besides background or foreground can't equal XmAS_IS in this place. So I just  removed this logic.
