• Fixed breaking related to rounding functions in “convertTransform”.
• Fixed a bug with ID in animations not being worked on by “cleanupIDs”.
• Fixed a bug with quoted reference in url().
• Now, if there are several same IDs in the document, then the first one is used and others are being removed.
• New command-line option --show-plugins displaying list of plugins.
• Two new optional plugins: “removeDimensions” (removes width and height if there is viewBox) and “removeAttrsPlugin” (by @bennyschudel).
