Comment 5 for bug 386494

I restored the offset values. Basically the workflow goes as follows:
1. Figure out where you want to justify (suppose top-left in this case) and set values. Note that it always snaps to the edge so that you can expect the text to be inside the image.
2. Figure out how much to offset (suppose we want to move the text a bit right and a bit down). In this case horizontal and vertical offset could be set to 5% or some other suitable value. Thanks to snap it's easier to estimate the offset value.

So the general rule is that positive values increment towards down/right (same as the old behavior!).

Note that I did not implement any other advanced options yet. Hopefully it's a bit better now. :)
