path, tools, pdb: UX updates to vector layers This patch improves vector layer UX based on feedback. In summary: * Makes vector layer editable from the Path tool * Adds initial PDB for creating vector layers in scripts * Size vector layers to the path size, rather than image * Transform tools utilize the path for resizing * Path tool automatically selects vector layer path
