/**
 * SVGKit's version of UIImageView - with some improvements over Apple's design
 
 WARNING 1: CAAnimations are NOT supported
 - because of the way this class works, any animations you add to the SVGKImage's CALayerTree *will be ignored*. If you need to animate the elements of an SVG file, use SVGKLayer instead (although that class is missing some of the features of this class, and is a little harder to use)
 
 WARNING 2: UIScrollView requires special-case code
 - Apple's implementation of UIScrollView is badly broken for zooming. To workaround this, you MUST disable the auto-redraw on this class BEFORE zooming a UIScrollView. You can re-enable it after the zoom has finished. You MUST ALSO make a manual call to "fix" the transform of the view each time Apple sends you the "didFinishZooming:atScale" method. There is an example of this in the demo project (currently named "iOS-Demo.xcodeproj") showing exactly how to do this. It only requires 2 lines of code, but Apple's documentation makes it clear that this is the only way to work in harmony with UIScrollView's internal hacks.
 - to disable auto-redraw-on-resize, set the BOOL: disableAutoRedrawAtHighestResolution to FALSE
 
 Basic usage:
 - as per UIImageView, simpy:
 - SVGKImageView *skv = [[SVGKImageView alloc] initWithSVGKImage: [SVGKImage imageNamed:@"image.svg"]];
 - [self.view addSubview: skv];
 
 Advanced usage:
 - to make the contents shrink to half their actual size, and tile to fill, set self.tileRatio = CGSizeMake( 2.0f, 2.0f );
 NOTE: I'd prefer to do this view UIViewContentMode, but Apple didn't make it extensible
 - to disable tiling (by default, it's disabled), set self.tileRatio = CGSizeZero, and all the tiling will be side-stepped
 - FOR VERY ADVANCED USAGE: instead of this class, use the lower-level "SVGKLayeredImageView" class, which lets you modify every individual layer
 
 Performance:
 - NOTE: the way this works - calling Apple's renderInContext: method - MAY BE artificially slow, because of Apple's implementation
 - NOTE: you MUST NOT call SVGKImage.CALayerTree.transform - that will have unexpected side-effects, because of Apple's implementation
 (hence: we currently use renderInContext:, even though we'd prefer not to :( )
