WebP and AVIF image support

[Glavo]

Hi,

The image formats supported by JavaFX have not been updated for a very long
time. However, more and more content providers are now adopting newer
formats such as WebP and AVIF.

For example, our application needs to display icons for Minecraft mods,
modpacks, and other content sourced from Modrinth, and the vast majority of
these icons are in WebP format. To work around this, we currently have to
bundle TwelveMonkeys into our program, decode the images to BufferedImage,
and then convert them to javafx.scene.image.Image. This approach
significantly increases the size of our application, adds considerable
performance overhead, does not support animated WebP, and even has a
color-shift bug when decoding lossy-compressed WebP images.

Is there any possibility that JavaFX will add native support for modern
image formats like WebP and AVIF in the future? I noticed that the
javafx.web module already depends on libwebp during its build, yet this
dependency is not utilized for javafx.scene.image.Image decoding—which is
honestly a bit of a shame. We sincerely hope that JavaFX can provide native
support for these formats.
