also common in Unix world) syntax is provided: the _() macro is defined to
do the same thing as wxGetTranslation().
If @a context is not empty (notice that this argument is only available
starting from wxWidgets 3.1.1), item translation is looked up in the
specified context. This allows to have different translations for the same
string appearing in different contexts, e.g. it may be necessary to
translate the same English "Open" verb differently depending on the object
it applies to. To do this, you need to use @c msgctxt in the source message
catalog and specify different contexts for the different occurrences of the
string and then use the same contexts in the calls to this function (or
wxGETTEXT_IN_CONTEXT() or wxGETTEXT_IN_CONTEXT_PLURAL() macros).
This function is thread-safe.
@note This function is not suitable for literal strings using wxT() macro
