- Fixed rotation matrix
- Fixed unneeded deformation caused by interior transformation for
  used objects (different tags should be handled differently),
  also, SYMBOL tag could have viewBox
- Implemented parsing of colors in rgb(r,g,b) notation

- Fixed exception caused by spaces after last semicolon in style
- Ignore svg namespage in tag names when detecting geometry class

- Remove unneeded "global" specificaitons
- Fixed parsing for paths which contains floating-point numbers
  in format like 10e-2
- Fixes aspect ration when viewBox is specified

 - Rect
 - Circle
 - Ellipse
 - Line
 - Polyline
 - Polygon

 Also fixed incorrect constant for cm/mm scaling

- Fixed silly error caused by copy-pasteing code from class
  (accessing to self from simple function)
- Fix for illustrator path format -- it doesn't place spaces before
  "minus" sign of next number. Maybe it's time to go out from stypid
  string replacement-splitting to slower but smarter token parser?

- 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 :)
