Please add preview support for GIMP's native .xcf format within Proton Drive Photos.

Many privacy-conscious creators use Proton alongside open-source creative tools like "GNU Image Manipulation Program" (GIMP) instead of Adobe Photoshop.

Currently, Proton Drive Photos does not recognize .xcf files as generic binary files. If Proton Drive Photos could recognize and generate thumbnails for .xcf files, it would be much easier for open-source photographers and digital artists to manage their active, layered project files securely.
