// Ok, let's explain why this method uses the "new" keyword.
// In the olden days (before September 2009) the user would call
// FlatRedBallServices.Load<TypeToLoad> which would investigate whether
// the user passed an assetName that had an extension or not. Then the
// FlatRedBallServices class would call LoadFromFile or LoadFromProject
// depending on the presence of an extension.
//
// In an effort to reduce the responsibilities of the FlatRedBallServices
// class, Vic decided to move the loading code (including the logic that branches
// depending on whether an asset has an extension) into the ContentManager class.
// To keep things simple, the FlatRedBallServices just has to call Load and the Load
// method will do the branching inside the ContentManager class. That all worked well,
// except that the branching code also "standardizes" the name, which means it turns relative
// paths into absolute paths. The reason this is a problem is IF the user loads an object (such
// as a .X file) which references another file, then the Load method will be called again on the referenced
// asset name.
//
// The FRB ContentManager doesn't use relative directories - instead, it makes all assets relative to the .exe
// by calling Standardize. However, if Load is called by XNA code (such as when loading a .X file)
// then any files referenced by the X will come in already made relative to the ContentManager.
// This means that if a .X file was "Content\myModel" and it referenced myTexture.png which was in the same
// folder as the .X file, then Load would get called with "Content\myTexture" as the argument. That is, the .X loading
// code would already prepend "Content\" before "myTexture. But the FRB content manager wouldn't know this, and it'd
// try to standardize it as well, making the file "Content\Content\myTexture."
//
// So the solution? We make Load a "new" method. That means that if Load is called by XNA, then it'll call the
// Load of XNA's ContentManager. But if FRB calls it, it'll call the "new" version. Problem solved.
