The Scaler II MegaCore function currently does not offer the nearest neighbor and
bicubic scaling modes, and the symmetric coefficient functionality is disabled for both
horizontal and vertical coefficients. You must specify the coefficients at run time for
version 10.1. However, you can achieve bicubic scaling by setting the horizontal and
vertical taps to 4 and load bicubic coefficients through the Avalon-MM control port.
