* regTestSetup()

* Input: argc (from invocation; can be either 1 or 2)

* "generate", "compare", "display")
* &rp (<return> all regression params)
* Return: 0 if OK, 1 on error
*
* Notes:
* (1) Call this function with the args to the reg test.
* There are three cases:
* Case 1:
* There is either only one arg, or the second arg is "compare".
* This is the mode in which you run a regression test
* (or a set of them), looking for failures and logging
* the results to a file. The output, which includes
* logging of all reg test failures plus a SUCCESS or
* FAILURE summary for each test, is appended to the file
* "/tmp/reg_results.txt. For this case, as in Case 2,
* the display field in rp is set to FALSE, preventing
* image display.
* Case 2:
* The second arg is "generate". This will cause
* generation of new golden files for the reg test.
* The results of the reg test are not recorded, and
* the display field in rp is set to FALSE.
* Case 3:
* The second arg is "display". The test will run and
* files will be written. Comparisons with golden files
* will not be carried out, so the only notion of success
* or failure is with tests that do not involve golden files.
* The display field in rp is TRUE, and this is used by
* pixDisplayWithTitle().
* (2) See regutils.h for examples of usage.
