lib: Introduce Clapper GTK integration library
An easy to use GTK integration library. Meant as a GtkVideo alternative. While GtkVideo is more of a simple example of video playback under GTK4, this acts as a full-fledged video player in the form of a GtkWidget that can be placed anywhere within application. The widget offers customization options for both top header and bottom playback controls panels. The Clapper playback API is exposed under widget "player" property making it easy for the programmer to set media and control playback programically. The new library will be distributed with Clapper player. This includes public headers and GObject Introspection support. Licensed under LGPL-2.1-or-later.
