Copy the target attributes that are easy to copy and make sense to
preserve under Windows too instead of only doing it under Unix in
wxTemp{F,}File and do it in a new wxFileName::CopyAttributesFrom()
function instead of duplicating the same code in both classes.
The new function can be potentially useful on its own, so make it public
and document it.
Add a unit test verifying that the attributes are preserved after
overwriting the file with wxTemp{F,}File.
This directory contains tests for the library and is mostly useful for the
library developers. See the samples subdirectory for the examples that are
more useful to the application developers using the library.
If you do work on the library itself and would like to modify an existing or
add a new test, please see docs/contributing/how-to-write-unit-tests.md for
more information.
This file also contains the instructions for running the tests if you'd just
like to do it to confirm that the library works correctly.
