Log Message:
Add metadata.xml for the SWC themes so that if Builder imports them they have nice names, etc.  These need to be updated by the Builder team if we end up changing how sourceLocation works, etc.  Also would be good if we added metadata.xml for the CSS versions.

Note the last paragraph in the original post which explains how Flickr handles resolution changes without breaking the rectangles. Perhaps a more straightforward approach would be to store both the rectangle coordinates for each rectangle AND the image's width and height at the time the rectangles were created. Then if the image is scaled, the rectangles can be scaled accordingly. For example, if a rectangle is at x=100,y=200,w=50,h=70, the "original dimensions" are 1000x2000, and the image's current dimensions are 500x1000, then an application could assume the image has been scaled down by (500/1000=) 0.50, and so the x,y,w,h of each rectangle could also be multiplied by 0.50 (x=50,y=100,w=25,h=35). I'd recommend storing floating-point values so that multiple scalings don't make the rectangles "creep".
Of course, it is possible that really the image was cropped rather than scaled, but fairly unlikely you would happen to crop it the same percent in both directions. Even if an image is cropped, someone could manually repair the rectangles by sliding and scaling them until the fit back on the faces (unless most of the faces were cropped off).
A rectangle-aware application could scale and translate the rectangles during a crop or scaling operation, but other applications could still survive scaling if they at least preserve the XMP tags as-is.
