Int8List getMatrix()

Fetches luminance data for the underlying bitmap. Values should be fetched using: {int luminance = arrayy * width + x & 0xff}

@return A row-major 2D array of luminance values. Do not use result.length as it may be larger than width * height bytes on some platforms. Do not modify the contents of the result.
