The hardness property has been renamed stroke-hardness. Something else
has broken elsewhere in GEGL at some point as well since fixing that
still doesn't seem to cause any rendering to happen.

The source code itself, including comments in the headers of the
GeglNode and GeglOperation classes are the only proper reference of
how this is currently implemented.
