Browse Source

This MR adds read-only QOI (https://qoiformat.org/) image format support for KImageFormats.

This format has received it's MIME type inclusion in shared-mime-info 4 months ago: https://gitlab.freedesktop.org/xdg/shared-mime-info/-/commit/ff51a0a9e36185288576ca32da9a8fa4bd2e6e90

The code is based on the reference QOI implementation at https://github.com/phoboslab/qoi/blob/master/qoi.h

Official test images: https://qoiformat.org/qoi_test_images.zip
