wxDEPRECATED must be used for the entire declaration to really work, but this wasn't the case for a few functions (and one typedef) guarded by WXWIN_COMPATIBILITY_2_8, resulting in gcc -Wattributes warning about the attribute being ignored and the declaration not being really marked as deprecated. Fix this by applying the deprecation macro to the entire declaration, which works well for gcc and should hopefully work for MSVC too.

A validator has up to three purposes:
|

|
|
1) To validate the data in the window that's associated
|
|
with the validator.
|
|
2) To transfer data to and from the window.
|
|
3) To filter input, using its role as a wxEvtHandler
|
|
to intercept e.g. OnChar.
|
|

Note that wxValidator and derived classes use reference counting.
