FR: Shadow offsets without showing solid lines

[Oneechan69]

Below is my shadow config, if I max the range much higher (to like let's say, 100) then you can clearly see there's as much of a shadow on top as there is on the bottom. You can specify an downwards offset but then there's clearly a solid line at the bottom of the window before the shadow.

I'm suggest the following:

• Changing the scale option from a float to a vec2 for vertical and horizontal scale.
• Factor in the offset when rendering? Like if the offset is a very high value then don't show solid lines outside of the window.

    shadow {
				enabled = true
				range = 40
				render_power = 3
				ignore_window = false
				offset = 0 5
				scale = 0.99
                                color = rgba(1a1a1a80)
				# color_inactive = rgba(1a1a1a)
    }

I'm want shadows look like macOS:
