// SVGImageForContainer contains a reference to an SVGImage and includes context
// about how the image is being used (size, fragment identifier).
//
// The concrete size of an SVG image is calculated based on the image itself and
// the dimensions where the image is used (see: SVGImage::ConcreteObjectSize).
// This concrete size cannot be stored on the SVGImage itself because only a
// single SVGImage is created per SVG image resource, but this SVGImage can be
// referenced multiple times by containers of different sizes. Similarly, each
// use of an image can have a different fragment identifier as part of its URL
// (e.g., foo.svg#abc) which can influence rendering.
//
// For example, the following would create three SVGImageForContainers
// referencing a single SVGImage for 'foo.svg':
// <img src='foo.svg#a' width='20'>
// <img src='foo.svg#a' width='10'>
// <img src='foo.svg#b' width='10'>
//
// SVGImageForContainer stores this per-use information and delegates to the
// SVGImage for how to draw the image.
