[wktraster] Getting regress failures and some expected output files are blank

[robe]

Not sure if thsi is because some things are not finished, but I don't recall getting regression failures on my last build.

On latest trunk all pass except

rt_box2d. failed (diff expected obtained: /tmp/rtpgis_reg_3012/test_5_diff)

This might be due to last change Jorge was working on.

Output of file is

*** rt_box2d_expected	Sat Jul 25 15:20:01 2009
--- /tmp/rtpgis_reg_3012/test_5_out	Sun Apr  4 12:26:56 2010

+ 2|BOX(7.5 2.5,12.5 7.5)|BOX(7 2,12 7)

This might be an error in the tests than testing itself. Because when I look at the expected output file, its hmm completely blank.

In fact there are 9 expected output files that are completely blank (looks like all done in a commit a year ago by Mat in r3940 ) http://trac.osgeo.org/postgis/browser/spike/wktraster/test/regress

Perhaps these are just place holders, but just noting it as a bit odd.

Some regression test output nothing if they are successfull.
