All main render pipelines (wire, hatch, image, mesh) now use 4× multisampling. Drawing passes render to a dedicated MSAA color buffer; a final empty resolve pass transfers the anti-aliased result to the iced surface target. The ViewCube renders post-resolve at 1× to avoid pipeline incompatibility. Depth buffer also upgraded to 4× MSAA. Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
