`unfiterable : true` indicates that the sampling of the texture will not apply filtering. This is mainly to satisfy the webgpu requirement for bindGroupLayouts. - Documentation has been updated for both `unfilterable` and `multisample`. - Internal materials have been updated where necessary (depth samplers have to be marked as `unfilterable`.) - webgpu code has been changed appropriately.
