wxWidgets/include/wx/msw/private/hiddenwin.h
Vadim Zeitlin b481194f51 No changes, just extract wxCreateHiddenWindow() declaration in a header.
Add wx/msw/private/hiddenwin.h with wxCreateHiddenWindow() declaration instead
of declaring it manually in all the files using it.

/*
Creates a hidden window with supplied window proc registering the class for
it if necessary (i.e. the first time only). Caller is responsible for
destroying the window and unregistering the class (note that this must be
done because wxWidgets may be used as a DLL and so may be loaded/unloaded
multiple times into/from the same process so we can't rely on automatic
Windows class unregistration).
pclassname is a pointer to a caller stored classname, which must initially be
NULL. classname is the desired wndclass classname. If function successfully
registers the class, pclassname will be set to classname.
