Modifies a transform such that a scaling occurs on any points multiplied by the transform.

The function `apply-scale`

modifies `
transform`
such that a scaling of `
sx`
in `
x`
and `
sy`
in `
y`
is performed on any points multiplied by the transform. Any operations already contained in the transform occur before the new scaling.

See graphics-state for details of how a transform is used.
