webp image format export support #1113
Description
Would propose to add export *.webp image format as WebP replaces GIF, JPG, PNG. Certainly PNG could remain but WebP would be appreciated to add. Also WebP has much less in file size and offers both lossless and lossy export. Would be good to choose while exporting or allow configure from settings. At version 2343 *.webp export was missing. Certainly it might require additional packages in Linux, e.g. libwebp, webp-pixbuf-loader. Current workaround is to make screenshot with program, that supports *.webp export, e.g. Flameshot.
