Proposed improvement: track browser scale/zoom, with function hooks to respond to changes

[KaliedaRik]

Issue

Similar to checking an SC Canvas artefact for changes in its dimensions and shape, it may also be useful to add checks and function hooks to the repo code base to allow dev-users to add functionality to their project which responds to changes in page scale/zoom levels.

Considerations

• Browser-level scale data can be retrieved from the window.visualViewport.scale read-only attribute.
• There's no media query in current (Media Queries Level 4) or future (Level 5) specifications that target the device viewport's scale/zoom level.
• Maybe check and update the current scale/zoom value as part an existing SC system animation's functionality?
• There will be an interplay between canvas size and shape, and the browser's scale/zoom value - how would such combinations be presented to dev-users?
• Should they be combined internally to simplify the API for dev-users or presented as-is so dev-users can make their own choices?

Solution and action

None determined yet.
