Re: [screen-wake-lock] An element attribute proposal for increasing screen brightness (#348)

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>
```
