Make the voidFilter into canvas.visibility.vision.light.global conditional.
- canvas.visibility.vision.light graphics is now in canvas.visibility.vision.light.sources
Apply blendMode to the dynamic illumination meshes for drawing or erasing, rather than relying on the shader's color.
Conditionally draw or erase the dynamic illumination meshes as there are cases where they are unnecessary.
