FBXLoader: Fbx Models containing .tif-format textures do not work

hey When I use an fbx model with a .tif-format texture, I find that the texture is not displayed on the browser. This raises some questions, and I hope to find answers.

1. Why wasn’t support for .tif-format textures considered? After consulting some information and related issues(#436), I learned that many browsers do not natively support .tif-format textures. By observing the source code of ImageLoader, I found that three.js works by displaying images through img tags. Is it possible to make three.js support .tif-format by extending ImageLoader? In fact, I made the image display by modifying the ImageLoader component, using tiff.js to load the tiff resource, and using canvas to convert it to png.

2. Another problem is derived from the above problem. FBXLoader does not seem to provide any extensibility. Each subcomponent is directly new in the method. When I want to modify or extend the logic of some subcomponents, I have to put the entire FBXLoader Taking it out for modification alone makes the modification cost very large and is not conducive to subsequent maintenance. May I ask if this is the original intention of the original design (do not want others to modify the source code) or other reasons?

If you okay with UTIF.js, I’ll file a PR 👍 .
