Optimize polar chart radius calculation a bit....
Optimize polar chart radius calculation a bit. Current algorithm still results in an occasional extra unneeded iteration, as it uses only crude approximation for radius reduction. However, any speedup gained by accurately calculating needed reduction would be very minor compared to approximations used, so it doesn't seem worth the effort to figure out the complex math.
