2035971 - RemoteImageProtocolHandler needs an option to preserve intrinsic aspect ratio

Status: ASSIGNED

Description

Desktop Firefox's urlbar recently started using the moz-remote-image protocol to load images (bug 2012436). RemoteImageProtocolHandler doesn't attempt to preserve intrinsic aspect ratios and instead uses the size specified in the URL, which distorts images that aren't square. I have a wallpaper fix in bug 2035353 that I'd like to uplift, but ideally RemoteImageProtocolHandler would provide a way for consumers to request that the aspect ratio be preserved.

Attachment: Bug 2035971 - Add preserveAspectRatio param to the moz-remote-image protocol.

This adds a boolean preserveAspectRatio param to the protocol. When true, the
minimum requested dimension becomes the minimum dimension in the final image
such that its intrinsic aspect ratio is preserved.
