Pixel test differences for three machines (as of r19001)

This file lists tests that failed on at least one of three machines (a build
slave <http://build.webkit.org/post-commit-pixel-powerpc-mac-os-x/builds/3397>,
an iMac G5 and a MacBook Pro, the latter two running Mac OS X 10.4.8). For each
test, the three numbers are the distance from the expected result observed by
each of the machines (in decreasing order). The tests are listed in descending
order of the biggest difference. The difference metric is the maximum over all
pixels of the L_1 distance (sum of absolute differences of R, G and B) between
actual pixel and expected pixel.

Hopefully I will follow up with some analysis. (What I really should have
measured was the distances between the different machines' actual results, but
laziness and total lack of {perl,python,ruby} fu have so far stopped me from
doing it).
