BUG: Returned wrong value

This test reported failure when it passed because it returned the
wrong value form RegressionTestImage. Since it was missing a
regression baseline, which causes a test to fail, it reported passing
the test.

A comedy of errors you might say.

DOC: Fix clang warning unknown command tag name

Replace back-slash prefix for doxygen command with at-sign prefix.
This may eliminate the clang warning. at-sign seems to be the
preferred doxygen command prefix in VTK.
