Infinite loop in SvgRadialGradientServer CalcScale Issue #163

Fixed some spelling mistakes

Fixed #145 - SVG incorrectly renders <title> elements.

SvgDocument as Write(XmlTextWriter); allowed elements to decide whether or
not they should be written. E.g. text elements should not be written
unless they have children.

Fixed many attribute enums. Now they will 1) output the proper case, 2) only output if non-null and non-default, 3) include more documentation, 4) are marked as Flags where appropriate.

Revert "Working on making this export valid SVG documents."
