Re: [mediacapture-image] Determine how PTZ permission prompts are supposed to work (#243)

When building the PTZ permission prompt in Chromium we considered prompting on `applyConstraints()` in addition to `getUserMedia()`. The reason we chose not to is that as you say it would require a PTZ-specific permission prompt to "upgrade" the existing permission to access the camera. We wanted to ensure that all camera-related permission requests were made upfront and with full context for the user rather than piecemeal.

Do you think this is a place where implementations could reasonably disagree or should the specification mandate or forbid supporting a permission request as part of `applyConstaints()`?
