 I don't think we should use events here as we don't use them for anything
related to determining the window sizes anywhere else. So it would be
better to have Set/GetAcceptableMaxSize() (please note that we shouldn't
use words like "best" here to avoid confusion with the existing functions
and that it should be explained in both the docs and the comments what
these functions are for in a way clear even for people who have no idea
about Macs).

 However I wonder if SetAcceptableMaxSize() is needed at all in fact.
AFAICS this size would be normally computed from the current contents of
the window and so IMO it doesn't make much sense to set it. Instead what
about just adding virtual GetAcceptableMaxSize() returning wxDefaultSize by
default but which could be overridden and would be used by wxMac?

 Thanks,
