v7

Refactor

[x] Make r3f and three dev-deps
[x] remove pixelratio - use dpr
[x] make PerformanceMonitor optional(pass in as child) - now called DprScaler in stdlib
[x] use standard flat / linear settings
[x] remove old noEvents flag - events on by default
[x] ~Remove VirtualScrollbar~ (decided to keep until proven not useful)
[x] fix zustand subscribe warnings
[x] render always by default - no need to call invalidate or requestRender for basic use case
[ ] Consider skipping requestRender requirement for basic "demand" frameloop

[x] HijackedScrollbar: lerp=1 on space, arrow, tab scrolling + dragging scrollbar
[x] HijackedScrollbar: fix history scroll position
[ ] BUG: config override scrollLerp on GlobalCanvas not working when using scrollbar

quick to get started
- render always
- no need to call requestRender or invalidate
minimize "clever" code - use basic R3F for most
Scroll rig is mainly synching WebGL and Scrollbar - that's it! Other things should be optional

By default frameloop="always"

Always render global loop
Add a viewport -> will cause double render
Adding a global child -> always renders even if hidden = OK for most scenarios. Most projects will not need otpimizing

By settings frameloop="demand"

Only render global loop if requested
Adding a viewport -> won't cause a global render unless needed
Adding a global child > will need to call both invalidate() and requestRender() to be visible = VERY advanced - only useful if sometimes only viewports/scissors are visible

Advanced:
