Consider adding elaborate tooling

[johannesvollmer]

The C++ library offers various other tools such as an image display app.

This serves multiple purposes, most importantly, it provides a real life example on how to use the library.

Also, color conversion and other features may be useful to users of the library.

isn't an image display app something the actual implementing App (like Maya) would implement? I think this library should be as clean as possible and only expose functionality for reading and writing EXRs appropriately. I guess color conversion could be a subdomain of reading an EXR, since this could be a task, specific to EXRs.

I would suggest a new Repo for the image display app which includes exr-rs as a library. This will also separate the business logic code strictly from the exr-rs library code.

Sounds appropriate. The image viewer should be more of an elaborate example than a real app.

I guess Azul is one of the most promising gui libraries, that would finally be a reason to try it out ^^
