in vector symbols, if any of the coordinates contain negative values, or if min(x) or min(y) is not exactly 0, then the size calculations and the positionning of the symbol is incorrect.
people used these kind of point coordinates to be able to offset the rendering of vector symbols, but this kind of usage is now unnecessary as we have ANCHORPOINT support
I suggest that we now translate the input vector points to ensure they are all positive and that min(x) = min(y) = 0
