HAS_
This variable should be used when rendering long lines, meaning longer than ~2 in 3d. WorldRenderEnvironment.longLines is available for this.
Context: For some reason, newer drivers for AMD Vega iGPUs (about end 2023 until now) fail to correctly smooth lines.
This has to be removed or limited to old driver versions when AMD actually fixes the bug in their drivers. But as of now, 01.02.2025, they haven't.
