Should "just work" for any TextureResource::get("*.svg"). dynamic_cast it to an SVGResource and call rasterizeAt(w, h) if you need to re-rasterize it.
Only supports scaling that maintains aspect ratio.
The ResourceManager provides a unified interface for accessing resource
data, embedded or from the filesystem, with
initialization/deinitialization handled automatically behind the scenes.
It also keeps from creating duplicate resources (e.g. when two
ImageComponents use the same image file).
Audio still needs to be moved over to it.
