The glyph-orientation-vertical attribute affects the amount that the current text position advances as each glyph is rendered.

The unsigned right shift (>>>) operator returns a number whose binary representation is the first operand shifted by the specified number of bits to the right. Excess bits shifted off to the right are discarded, and zero bits are shifted in from the left. This operation is also called "zero-filling right shift", because the sign bit becomes 0, so the resulting number is always positive. Unsigned right shift does not accept BigInt values.

The path attribute has two different meanings, either it defines a text path along which the characters of a text are rendered, or a motion path along which a referenced element is animated.
