mem leak, window resize handler not removed

[trusktr]

three-projected-material/src/ProjectedMaterial.js

Lines 252 to 256 in 5e0ed6d

	window.addEventListener('resize', () => {
	this.uniforms.projectionMatrixCamera.value.copy(this.camera.projectionMatrix)
	this.saveDimensions()
	})

I don't see a dispose method, and that handler is never removed, so instances of this material can not be garbage collected.

Good catch!
