+A schnorr signature ((("digital signatures", "schnorr signature algorithm", "serialization")))((("schnorr signature algorithm", "serialization")))((("serialization", "of schnorr signature algorithm", secondary-sortas="schrnorr")))consists of two values, +kG+ and +s+.  The value
 +kG+ is a point on Bitcoin's elliptic curve (called secp256k1) and so
 would normally be represented by two 32-byte coordinates, e.g., +(x,y)+.
 However, only the _x_ coordinate is needed, so only that value is
