Making it possible to properly handle compositors that have those properties as doubles and handle antialiasing. Internally we were handling those values as doubles in framepositioner, so expose new properties so user can set values as doubles also. This changes the GESFramePositionMeta API but we are still on time for 1.24 Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/6241>
