That's one of the major benefits we should be able to get from eliminating
the IPO/Action mixture by just having a single type. I'm still thinking
through the best ways to present this information as channels in
Dopesheet/F-Curve Editors, but I hope it should be clear enough.

Currently I've got support for an 'envelope' modifier that could do such
things. This could give more flexibility than a simple bezier curve, as
you've got the option of stretching the values vertically in addition to
merely deforming them.

Action Editor tools are already ported to operators. However, the menu
entries for these are still not yet done :)

Also, the Timeline RNA (i.e. Markers) could get added. However, I think it's
more important to get constraints RNA done first.
