Point is defined as || Big-endian int16 || Big-endian int16 || Byte || || *X* coordinate || *Y* coordinate || *flags* || where *flags* are: || 8th bit || 7th bit || 6th-1st bits || || if set, this is a first point of polyline || if set, polyline is erasing || *width* (thickness) of line || … where *width* defines `(width * 10) + 6` pixels width line to draw. Second and further points of polyline have 8th bit of *flags* unset, the content of others are ignored for those. A single-point polyline defines a circle. == Sharing hand-drawn maps == Hand-drawn maps will be automatically transferred when playing online.
