Creates a hidden window with supplied window proc registering the class for
17
it if necessary (i.e. the first time only). Caller is responsible for
18
destroying the window and unregistering the class (note that this must be
19
done because wxWidgets may be used as a DLL and so may be loaded/unloaded
20
multiple times into/from the same process so we can't rely on automatic
21
Windows class unregistration).
23
pclassname is a pointer to a caller stored classname, which must initially be
24
NULL. classname is the desired wndclass classname. If function successfully
25
registers the class, pclassname will be set to classname.
