The `bl_context` class variable defines what mode the drawn property appears in, e.g. `bl_context=posemode` makes whatever drawn via the `draw` method appear only in the pose mode. What if we want the property to appear in both `objectmode` and `posemode`, and what are the values for other modes, like: `particle edit mode`, `vertex paint mode`, `sculpt mode`?

Now, this generates a panel, somewhat like this:
[![nice panel][1]][1]
Now, everything's nice and handy but, I want the "Facial Control" panel to appear both in `posemode`, `edit mode`, `object mode` and `sculpt mode`, and as you have seen in the code, this to my knowledge is controlled by the `bl_context` parameter, but, if the panel is to appear in all these modes, what should I set the `bl_context` parameter to?
