It is important to note that this doesn't always act on the selection (like it's usually done), it acts on a subset of it. E.g. the selection code may leave a hint that we just dragged on a left or right handle (SIPO_RUNTIME_FLAG_TWEAK_HANDLES_LEFT/RIGHT) and then we only transform the selected left or right handles accordingly. The points to be transformed are tagged with BEZT_FLAG_TEMP_TAG; some lower level curve functions may need to be made aware of this. It's ugly that these act based on selection state anyway.

Time-stepping auto-snapping modes don't get applied for Graph Editor transforms, as these use the generic transform modes which don't account for this sort of thing. These ones aren't affected by NLA mapping, so we do this after the conversion...

Note: We also have to apply to td->loc, as that's what the handle-adjustment step below looks to, otherwise we get "swimming handles".; We don't do this when canceling transforms, or else these changes don't go away.
