Previously the icon was made up of a tape measure and a pencil. But pencil icons normally mean editing something. It was not clear that this icon was meant to delete all the measurements. This commit replaces the pencil with a red X to make clear it deletes something. The X was taken because existing delte icons in FreeCAD also use a red X. - https://www.freecadweb.org/wiki/File:Mesh_Remove_Components.svg - https://www.freecadweb.org/wiki/File:OpenSCAD_RemoveSubtree.svg - https://www.freecadweb.org/wiki/File:Delete.svg
