Applies 2D filtering.

Pascal
function Filter2D(const Src: TMtx; const Kernel: TMtx; const SrcRect: TMtxRect; const KernelAnchor: TMtxPoint; const Buffer: TVecInt = nil): TMtx; overload;
Description

The result is stored in to the calling object. The size of the calling object is set to match SrcRect dimensions. 

Important: The allocated size of the destination will never be overwritten, but the value of samples on the edge of the Dst matrix could be computed from elements outside of the Src thus making them appear to be random, because uninitialized memory was being referenced, if the parameters are not set carefully.
