#6 PostProcess as a function: SampleBased

[Sid D]

A new noise is added, called SampleBased. It takes a double[][] sample array, and returns interpolated values ( bilinear or bicubic ). So post processes can be done in as much precision as you want and still it behaves like a noise. Hence any noise filters can be applied on it. Outside its boundaries, however, it can oly be zero, edge repeat or full repeat.

included are also, an Image based noise source ( paint ur own landscape and import... save landscape as image and import .... ), two erosion functions ( copies from libctod, HeatErosion and RainErosion ), and a example function SampledAccurateScale.

There are a few cosmetic changes to existing classes.
