JincResize-r3

• Change function name: core.ewa.Lanczos -> core.jinc.JincResize
• Change parameter: float radius -> int tap
  • The original meaning of this parameter is the zero points of Jinc function
  • In old versions, users need to enter the value of the zero point by themselves with radius. Of course, users can enter any float value, but deviating from the original meaning.
  • In the current version, we provide 16 zero points. Users can choose suited zero point with tap. With the increasing of tap value, the value of zero points increases.
  • In default settings, the old and current versions are the same.
• Modifying code, maybe speed up a little.
