Just to clarify this (as I read through some more sources):
Both DCs refer to the same top-level window, but to different 
containers (panels) within this window.
Device Contexts on Mac are associated with the top-level window. 
Thus, the DC's are the same.

I don't know how this is implemented on other platforms, i.e. what is 
the definition of "window" wrt. wxDC contexts.

Are we allowed to use a wxClientDC initialized for one panel to draw 
into another panel of these belong to the same window, alternatively, 
could we initialize a wxClientDC for the top-level container and use 
this to draw into all panels?
