[rrd-developers] rrdtool 1.3 cairo switch is done

[Dylan Vanderhoof]

Tried this on my test server.  Generated 515 graphs of ~30 days each.
Trunk functions fine and the graphs look good, but its substantially
slower than 1.2.23 w/ the fadvise patch.  (trunk compiled with mmap and
directio)

denver ~ # time cat rrds | xargs sh dotestgraphs.sh
Generated 515 graphs

real    2m13.567s
user    2m3.760s
sys     0m6.970s

dylanv at denver ~ $ time cat rrds | xargs sh dographs.sh
Generated 515 graphs

real    0m44.573s
user    0m43.090s
sys     0m1.310s
