MaskShader
Setup macros and layer variables used in MaskShaders.
Setup Macros
At the top of the vertex() function, declare SETUP_MASK_VERTEX.
At the top of the fragment() function, declare SETUP_MASK_FRAGMENT.
Layer Variables
A MaskShader can read LAYER_BLEND_* layer variables, referring to the Blend input of a MaskNode, and LAYER_BASE_* referring to the Base input of a MaskNode.
The LAYER_BASE_* layer variables return the accumulated properties of the layers from the Base input chain. The Blend input returns the properties of the SurfaceNode from the input chain. ( Blend input only takes in SurfaceNode )
