Simplify the code by more or less reverting c7619cf139 (Replace a
template function with template class to fix VC6 build., 2012-11-12)
which shouldn't be necessary any longer as VC6 is not supported since a
long time.
No real changes.
This commit is best viewed ignoring whitespace-only changes.
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.
