How can I set desktop icons to auto-align to the right side of the screen?

this has been a nautilus bug since they first came out with nautilus:

if you download the source you can look at it yourself: currently tbrl (top-bottom-right-left, the ordering you want) isn't implemented and just uses tblr instead. so you have to hack it yourself or wait for an official fix. there seems to be not much progress in it though.
