WebP and AVIF image support

[Kevin Rushforth]

We don't currently have any plans to add such support, but could 
consider it if there was enough demand.

Now that we have support for using Java2D's ImageIO an application could 
provide one or use a third-party ImageIO loader for those formats, but 
that would have similar limitations to those mentioned (it wouldn't 
support animated images and the application would need to bundle the 
loader).
