 				Sets the sharpening [code]intensity[/code] for the [code]viewport[/code]. If set to a value greater than [code]0.0[/code], contrast-adaptive sharpening will be applied to the 3D viewport. This has a low performance cost and can be used to recover some of the sharpness lost from using FXAA. Values around [code]0.5[/code] generally give the best results. See also [method viewport_set_use_fxaa].
