Function convolveMutateGrid

convolveMutateGrid<TCell, TKernel>(
    kernel: Kernel<TKernel>,
    source: UniformGrid & { set: GridCellSetter<TCell> } & {
        get: GridCellAccessor<TCell>;
    },
    reduce: KernelReduce<TCell, TKernel>,
    blend?: (conv: TCell, original: TCell) => TCell,
    visitor?: Iterable<GridCell, any, any>,
    origin?: GridCell,
): UniformGrid & { set: GridCellSetter<TCell> } & {
    get: GridCellAccessor<TCell>;
}
Performs kernel-based convolution over a grid, mutating the source grid with the results.
```
const gridData = Grids.Array2d.wrapMutable(gridArray);
Convolve2d.convolveMutateGrid(
   Convolve2d.gaussianBlur3Kernel, // Use the Gaussian blur kernel
   gridData,  // Provide grid values in an accessible form
   Convolve2d.averageNumberReducer,
   (conv, original) => {
     return interpolate(0.1, original, conv);
  }
);
```
Type Parameters
- TCell
- TKernel
Parameters
- kernel: Kernel<TKernel>
  Kernel data
- source: UniformGrid & { set: GridCellSetter<TCell> } & { get: GridCellAccessor<TCell> }
  Source data
- reduce: KernelReduce<TCell, TKernel>
  Function to combine values at a position
- Optionalblend: (conv: TCell, original: TCell) => TCell
  Optional function to blend the convolved value with the original value. If not provided, the convolved value will replace the original value.
- Optionalvisitor: Iterable<GridCell, any, any>
  Visitor to iterate over the source grid. If not provided, all cells will be visited.
- Optionalorigin: GridCell
  Optional origin of the kernel. If not provided, the center of the kernel will be used.
Returns UniformGrid & { set: GridCellSetter<TCell> } & { get: GridCellAccessor<TCell> }
Returns 'source' grid, which has been mutated with the results of the convolution.
