Title: Performance Improvement

- Because querying the Bounds property of an ISvgBoundable or
SvgVisualElement is expensive, we introduced an ImmutableBoundable that
is used by the SvgRenderer. This class stores the bounds of the supplied
ISvgBoundable so that multiple queries for the bounds do not hamper
performance when rendering.

- Converted the Bounds property on ISvgBoundable and SvgVisualElement to a
CalculateBounds method to indicate that it is an expensive operation
that returns a new value each time it is called.

- Removed redundant ISvgBoundable Location and Size properties.

- Fixed a bug in SvgFragment.Path property by converting it to a method that
indicates it returns a new GraphicsPath instance when called and by
disposing of that instance in CalculateBounds. There are many more
instances of GraphicsPath not being disposed in the code base but we did
not address that here.
