Describe the issue you are experiencing

If I live view a camera with native 16:9 resolution in a picture entity card, the image comes out vertically stretched.
Then I enter the variable aspect_ratio: “16:9”, and I see that the image is reproportioned correctly, but looking closer I notice that actually the camera image is truncated at the bottom.
In other words, it is the card that is reproportioned, not the camera image.

Code example:
type: picture-entity
entity: camera.telecamera_portico_profile001
camera_view: live
aspect_ratio: "16:9"
show_state: false
show_name: false

Describe the behavior you expected

Since aspect ratio is a parameter that relates to the image (or video), I expect the parameter to act on the card by also reproportioning the image, which will then not be deformed.
In theory this should also avoid unnecessary recalculations, the image being displayed as is.
