made use the renderset's frame dimensions, instead of hard-coded values
removed ImageAsset.asImage and it's usages
deprecated the URL-only constructors in favor of URL:Dimension constructors, to avoid needless loading and measuring of assets, as well as to support non-BufferedImage and other unmeasureable assets which are still otherwise usable for composition
fixed indentation
moved the Align enum out of AwtCompositor so it can be used by others
whole bunch of playing with the SVG compositor.  Text measuring is even more broken than on the AWT compositor, and I don't know why.  The math is right, but the actual text rendering does not match the measurements.
empty placeholder transcoder with a couple transcoding tests that are more POCs than actual tests
