Treemap for sysprof

[Andy Somerville <andy somerville gmail com>]

Hi,

I'm a big fan and user of sysprof.

After using applications which visualize resource allocations using
treemaps, sysprof seems to me to ripe for just this feature. It's one
I would greatly appreciate myself.

Three examples of applications implementing this (with slightly
different treemap concepts) are  gdmap, baobab and kcachgrind (which
incidentally is used very similarly to sysprof)

Example screen shots:

  gdmap:       http://gdmap.sourceforge.net/img/gdmap-preview.png
  baobab:      http://library.gnome.org/users/baobab/stable/figures/baobab_fullscan.png.en
  kcachegrind: http://kcachegrind.sourceforge.net/shot3-02.png

I've started to hack apart gdmap to pull out its treemap
implementation for a proof of concept for sysprof.

If there's interest I'd be interested in cleaning it up for
integration, or trying to do the same for baobab's ring based treemap
if there was more interest there.
