To support the WebXR permission prompt and status indicator, we need notification icons in SVG format.

• webxr.svg will be displayed in the URL bar, representing WebXR activity.
• webxr-blocked.svg will be displayed in the URL bar, representing WebXR activity that was blocked.
• webxr-detailed.svg should represent a larger WebXR icon for display within the permission dialogue.

For reference, the geolocation api has icons with the same metrics and for the same purpose:

• geo.svg
• geo-blocked.svg
• geo-detailed.svg

These are viewable from within the browser:

• chrome://browser/skin/notification-icons/webxr.svg
• chrome://browser/skin/notification-icons/webxr-blocked.svg
• chrome://browser/skin/notification-icons/webxr-detailed.svg

These icons are located in the tree:

browser/themes/shared/notification-icons/

If they must be different for each platform, they would be located in platform specific folders:

browser/themes/linux/notification-icons
browser/themes/osx/notification-icons
browser/themes/windows/notification-icons

SVG icons representing VR and AR are required for permission prompts and status

Final / non-dev-art icons added. Thanks to Jenni and Nadja!

This has been included in Bug 1580567, which has landed.
