/// Converts a bitmap to 1-bit monochrome bitmap using a threshold T between [0..255].
/// The function first converts the bitmap to a 8-bit greyscale bitmap. Then, any brightness
/// level that is less than T is set to zero, otherwise to 1. For 1-bit input bitmaps, the
/// function clones the input bitmap and builds a monochrome palette.
