+/*!RDG_genBuffer
+ Generate 'size' bytes of compressible data into 'buffer'.
+ Compressibility can be controlled using 'matchProba', which is floating point value between 0 and 1.
+ 'LitProba' is optional, it affect variability of individual bytes. If litProba==0.0, default value will be used.
+ Generated data pattern can be modified using different 'seed'.
+ For a triplet (matchProba, litProba, seed), the function always generate the same content.
+
+ RDG_genStdout
+ Same as RDG_genBuffer, but generates data into stdout
