Description

The for loop in file thinplatespline.h:74​ has 3 static iterations: 

     for ( int i = 0; i < 3; i++ )
                rhs[i][v] = 0.0;

and with rhs being defined as 

#define VIZGEOREF_MAX_VARS 2
double *rhs[VIZGEOREF_MAX_VARS];

leads to index out of range.

r20193 /trunk/gdal/alg/thinplatespline.h: Fix index out of range in thinplatespline.h (no bad effect was seen previously since rhs and coef should generally be packed one after the other one by the compiler) (#3705)

I completely removed the loop since grow_points() already takes care of zero'ing with VSICalloc. I also fixed the dump_data_points() which was inverting the order of the indices too (this function is unused)
