I am in the selector tool

I create a quickshape I click on the selector tool infor bar button - set origin position - and I get a rotation point that I can move so that the quickshape rotates around this

the position of the rotation point persists, which is how I understood it would work, and is good.... a make more quicjkshapes, they rotate around the rotation point as set

but this operation does not work for me with a bitmap - it will not rotate around the point so set, it just rotates around it's own centre; and I cannot get a rotation point to apperar on a bitmap when resetting with the infobar button
