MODIFIED: readme to list required frameworks.
ADDED: automatic simple support for 're-sizing' the rendering part of an SVG, so that it outputs a UIImage of the desired size
FIXED: temporary workaround for the fact we don't parse TSPAN elements, that uses DOM level 3 method on Node. Cleaned up all text parsing throughout the parser and the parser-extensions (text is now supplied as nodes, not as a string - this is REQUIRED for SVG TEXT nodes)
