Noel Grandin 6122f6266c fix memory management in BitmapConvolutionMatrixFilter
was deleting a stack allocated buffer.

Also
(*) drop the BitmapConvolutionMatrixFilter default constructor, the
current code does not permit mpMatrix to be nullptr
(*) declare the mpMatrix field as a reference to a fixed length array,
to be more precise
(*) pass the array in the constructor so that call sites will be
properly type- and length-checked.
