Functions
void	Save2DNoise (float **cell, const int n, const float scale, const char *basefilename)

Detailed Description

Two versions of the Save2DNoise function, one for Windows and one for Unix. The Windows version uses GDI+ code for saving a PNG image to a file. This code was mostly scored from the MSDN website, but getting the details right was like pulling teeth. The Unix version saves the noise tile as a TGA image because, frankly, the format is bog-easy and I could write the code in under 30 seconds. No excuses.
