// LuprexViewportClient.h
//
// Custom game viewport client.  Implements a project-wide
// click-to-focus rule: when a left-mouse-button click is
// not handled by any widget and bubbles up to the viewport,
// we hit-test under the cursor and focus the nearest
// focusable ancestor of whatever was hit.
