Properties

Name	Type	Description
`x`readonly	`number`	The corner the sprite grows from, and which corner depends on the affine. More In screen space y counts down, so this is the top-left; in a 2D world y counts up, so it is the bottom-left. The batch does not know which it is in and does not need to: it is the same arithmetic either way, and `camera2d.ts` is where the two conventions are written down.
`y`readonly	`number`
`w`readonly	`number`
`h`readonly	`number`
`rotation`readonlyoptional	`number`	Radians, anticlockwise in the mathematical sense — which reads as clockwise on screen, where y counts down. Defaults to none.
`pivotX`readonlyoptional	`number`	The point rotation turns about, as a fraction of the sprite. Defaults to its centre.
`pivotY`readonlyoptional	`number`
