Max resolution according to aspectratio

I would like to limit the size of the picture on the longest size of the picture.
So when the picture is taken in Landscape or Portrait mode, the longest size may not be heigher than for example 1920px.

Now you can set targetHeight and targetWidth.
When I set both to 1920px, the landscape version is width is higher than 1920px.

Start by tracing how targetHeight and targetWidth are handled for landscape and portrait captures. Verify the current dimensions and identify the camera implementation and tests covering these options. Done means the longest image dimension never exceeds the requested maximum while preserving the aspect ratio.
