Thanks for organising this, @beaufortfrancois.
I have a few questions:
1. Should this affect only certain elements like img, canvas, video etc?
2. How should layering elements and z-index work? For example, a canvas element with a translucent div overlay.
For (2), here are a couple of scenarios I can think of:
Wrapper has `increaseBrightness`:
```html
<div style="position: relative;" increaseBrightness>
<canvas style="width: 640px; height: 480px; z-index: 1" />
<div style="z-index: 2; position: absolute; top: 0; left: 0; width: 100%; height: 100%">
</div>
```
Lower layer has `increaseBrightness`:
```html
<div style="position: relative;">
<canvas increaseBrightness style="width: 640px; height: 480px; z-index: 1" />
<div style="z-index: 2; position: absolute; top: 0; left: 0; width: 100%; height: 100%">
</div>
```
