 wxGridTableBase has its own GetAttr(). By default it forwards to the
attribute provider but it could be overridden in a derived table (i.e.
model) class to return something else directly.

 OTOH I was wrong about combining the attributes with the attributes of the
grid because there are no attributes in wxGrid itself, sorry.

 Surely the implementation shouldn't matter provided they derive from the
same wxItemRenderer (currently known as wxGridCellRenderer) ABC?

 I realize that it might be easier to just implement wxDataViewCtrl stuff
independently but it would be really, really a pity to not reuse wxGrid
API here.
