[v1] Masked elements are off-set if canvas is not full screen

[alberto-salieto-scopely]

Hello,

Description Masked elements are off-set if canvas is not full screen.

It is caused by line 39 in SoftMask.cginc

half2 view = clipPos.xy/_ScreenParams.xy;

specifically _ScreenParams.xy. According to https://docs.unity3d.com/Manual/SL-UnityShaderVariables.html, it returns camera render size in pixels, not canvas size. Proposed fix is to pass offsets to calculate true canvas size and position.

Expected behavior The mask should be in the proper position according to the canvas position. In our case, canvas is displaced because of the notch, so it doesn't have the fullscreen size.
