you already can, and are "encouraged to do", adjust the global 'povray.ini' file
after installation; simply add the desired 'Width's and 'Height's ?
also, fwiw and afaik, I've not had any "non-square pixels and the output
appearing horizontally stretched" problems. (rendering 16:9 and 16:10 regularly
on a machine with a 5:4 monitor)
