[postgis-devel] test output

[strk]

I've finally handled to download Mark's data.
Here is the test output summary.

[lo:test_outputs]$ grep avg 52468-polygon-stats10-gain1                             1   (best/worst/avg)        0       0       +-0
    2   (best/worst/avg)        0.22    5.91    +-1.83
    4   (best/worst/avg)        0       6.07    +-1.47
    8   (best/worst/avg)        0       7.05    +-0.55
    16  (best/worst/avg)        0       10.51   +-0.25
    32  (best/worst/avg)        0       7.53    +-0.13

[lo:test_outputs]$ grep avg 52468-polygon-stats10-gainAOI
    1   (best/worst/avg)        0       0       +-0
    2   (best/worst/avg)        0       -1.07   +-0.38
    4   (best/worst/avg)        0       -3.11   +-0.59
    8   (best/worst/avg)        0       -2.95   +-0.22
    16  (best/worst/avg)        0       1.67    +-0.06
    32  (best/worst/avg)        0       -1.57   +-0.02

I've committed the gain = AOI/cell_area back in CVS.
