- Fixed incorrect usage of 255 color range -- each component should
  be from segment [0..1]
- Added "style" tag parsing

zero length bones had their tail offset in the wrong direction.

Only <path> is supported at this moment, other geometries would
be added a bit later. Transform attribute, defined, groups and
uses should work pretty fine.

Work is in progress, so please repoer issues to me, not to tracker :)
