Add a framework for reading and decoding stored graphical texture file formats. Includes decoders for the PKM and KTX formats. This is basically the same texture file reading that was added to qtdeclarative for 5.11, but has been refactored to be independent of the scenegraph and opengl. Task-number: QTBUG-67026 Change-Id: I87d8117550d8a2112f4f58c03e9ac6b3249cbc5a Reviewed-by: Kai Koehne <kai.koehne@qt.io> Reviewed-by: Laszlo Agocs <laszlo.agocs@qt.io>
