Release:
    * Engine
        + Benchmark harness
        + Reuse points, pack "nodraw" in high bit of stroke id (probably have at least one more bit, so up to 4 flag configurations)
        - Draw dynamic data (strokes in progress)
        - Textured quads (pictures, code already written in older version)
        - Resize and move pictures (draw handles)
        - Z-prepass fringe bug (also, when do we enable the prepass?)
        - Restore ability to limit event range
        - Only upload stroke data to texture as it arrives (texSubImage2D)
    - Listeners/events
        - Investigate skipped inputs on mobile (panning, zooming)
        - Save events to indexeddb (as some kind of a blob), restore on reconnect and page reload
        - Separate events and other data clearly (events are self-contained, other data is temporal/non-vital)
        - Do NOT use session id as player id LUL
        - Local prediction for tools!
        - Drag with mouse button 3
    - Missing features I do not consider bonus

        - Line drawing
        - Player screens/pointers
        - Follow player (like Ligma)

        - Undo/redo
        - Dynamic svg cursor to represent the brush
    - Polish
        - Show what's happening while the desk is loading (downloading, processing, uploading to gpu)

    - Presentation / "marketing"
        - Title
        - Icon

        - Move whole curve
        - Move single point
        - Move multiple points
