Add QtQuick3D and QtQuick Timeline.
QtQuick3D
Description from Qt [1]:
Qt Quick 3D provides a high-level API for creating 3D content or UIs based on Qt Quick. Rather than using an external engine which creates syncing issues, and additional layers of abstraction, we provide extensions to the existing Qt Quick scenegraph for spatial content, and a renderer for that extended scenegraph. When using the Spatial scenegraph it is also be possible to mix Qt Quick 2D content with 3D content.
QtQuick Timeline
Description from Qt [2]:
The Qt Quick Timeline module enables keyframe-based animations and parameterization. This module is directly supported by Qt Design Studio and Qt Quick Designer, with a timeline editor to create keyframe-based animations.
