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)
        + Webassembly for core LOD generation
        + Webassembly for final buffers
        + Do not copy memory to wasm, instead use wasm memory to store data in the first place
        + SIMD for LOD?
        + Multithreading for LOD
        + 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?)
        - Frame-independent lerp where applicable
    + Bugs
        + GC stalls!!!
        + Stroke previews get connected when drawn without panning on touch devices
        + Redraw HTML (cursors) on local canvas moves
        + New strokes dissapear on the HMH desk
        + Undo history of moving and scaling images seems messed up
        - Nothing get's drawn if we enable snapping and draw a curve where first and last point match
        - Weird clipping on HMH desk full zoomout after running "benchmark"
        - Stuck in color picker mode when mouse leaves screen 
    - Debug
        * Debug view for BVH
        - Restore ability to limit event range
    * Listeners/events/multiplayer
        + Fix multiplayer LUL
        + Fix blinking own stroke inbetween SYN->server and SYN->client
        + Drag with mouse button 3
        + Investigate skipped inputs on mobile (panning, zooming) [Events were not actually getting skipped. The stroke previews were just not being drawn]
        + Smooth zoom
        + Infinite background pattern
        + Be able to have multiple "current" strokes per player. In case of bad internet this can happen!
        - Do NOT use session id as player id LUL
        - Save events to indexeddb (as some kind of a blob), restore on reconnect and page reload
            - Handle out of space
        - Local prediction for tools!
            - Immediately commit a stroke to the canvas, change order if earlier strokes arrive
            - Show my own image immediately, show placeholders while images are loading (add bitmap size to event)
            - undo immediately, this one can not arrive out of order, because noone else is going to undo MY actions
    * Missing features I do not consider bonus
        + Player pointers
        + Pretty player pointers
        + Player list
        + Follow player
        + Color picker (or at the very least an Open Color color pallete)
        + EYE DROPPER!
        + Dynamic svg cursor to represent the brush
        + Eraser
        * Line drawing
            + Live preview
            ~ Alignment (horizontal, vertical, diagonal, etc) [kinda gets covered by the snapping? question mark?]
        + Undo
            + Undo for eraser
            + Undo for images (add, move, scale)
        - Redo
        + Snapping to grid
        - Snapping to other points?
        - Color picker should work for ruler
        - Show previous color in color picker preview
        - Stick picker preview to cursor
    * Polish
        + Use typedvector where appropriate
        - Show what's happening while the desk is loading (downloading, processing, uploading to gpu)
        - Settings panel for config values (including the setting for "offline mode")
        - Set up VAOs
        - We are calling "geometry_prepare_stroke" twice for some reason
        - Replace "geometry_add_dummy_stroke" with something not [so] cursed
        - Automatically extract locations from shaders (see nitka project for code examples)
    - Presentation / "marketing"
        - Title (InfiNotes? MegaDesk?)
        - Icon
        - Product page (github readme, demo videos)

Bonus:
    * Handle pressure
        + Add pressure data to quads
        + Account for pressure in quad/bbox calc
        + Adjust curve simplification to include pressure info
        + Migrate old non-pressure desks
        - Check out e.pressure on touch devices
        - Send pressure in PREDRAW event
    - Stroke smoothing
