What it is

Kinogaki viewport widgets for Kinogaki UI (lib-ui): one/four-view layout, camera navigation, the six-axis view cube, transform gizmo handles and point number labels. Applications draw the rendered view texture (from kinogaki-viewport-gpu) and route input through these pieces; what a gizmo drag edits stays with the application's editing context.
