Trim Paths, Merge Paths, Repeater and the other path operations
existed (layer.addShapeItem) but no menu added them to a shape layer.
Like After Effects, a shape layer's Contents row now has "Add:" with
Group, Rectangle, Ellipse, Polystar, Path, Fill, Stroke, Gradient Fill,
Gradient Stroke and the path operations; with a shape group selected
they go into it. layer.addShapeItem gains the empty Path and Gradient
Stroke kinds.
A 3D text or shape layer in a Classic 3D comp now shows Geometry
Options with "Change Renderer…", which opens Composition Settings on
its 3D Renderer tab (Advanced 3D comps show the extrusion options).
Popup menus are as tall as the window allows and open upward near its
bottom: the 20-entry Add menu was cut at 420 px, hiding Trim Paths.
Tests: shape_contents_add_menu_adds_path_operations,
classic_3d_shape_layers_offer_change_renderer.
