Problem with __plt_get_axis_arg__.m

[Michael Goffioul]

I have a problem related to the current implementation of __plt_get_axis_arg__:
it always return an axes object, even if the first argument is an handle to
something else, like an hggroup.

The problem popped up when adapting my barseries creation function.
Basically, it creates an hggroup, then it creates a patch as child of the
hggroup. The patch is simply created with:

patch(hggroup_handle, ...)

However, __plt_get_axis_arg__ is called from patch.m, which converts my
hggroup parent to the containing axes. As a result, the patch object is
created with the axes as parent, and not my hggroup.

How am I supposed to deal with this?
