Function fromPivot

Creates a line from an origin point.

// Line of length 0.2 with middle at 0.5,0.5
fromPivot({ x:0.5, y:0.5 }, 0.2);
// Same line, but on an angle
fromPivot({ x:0.5, y:0.5 }, 0.2, degreesToRadian(45));

// ...now with pivot point at 20%, rather than center
fromPivot({ x:0.5, y:0.5 }, 0.2, degreesToRadian(45), 0.2);

Examples:

Angle of 0 (deg/rad) results in a horizontal line,
Angle of 90deg in a vertical line.
Angle of 45deg will be angled downwards.

fromPivot(origin?, length?, angleRadian?, balance?): Readonly<{

Parameters
- origin: Point = ...
  Origin to pivot around
- length: number = 1
  Total length of line
- angleRadian: number = 0
  Angle of line, in radians
- balance: number = 0.5
  Percentage of where origin ought to be on line. Default: 0.5, meaning the middle of line
Returns Readonly<{
a: Point;
b: Point;
