    gsk: Deprecate GskGLShader and the rendernode · 32625381
    Benjamin Otte authored
    The new renderers don't support them due to the required complexity of
    integrating them with Vulkan and the assumptions those nodes make about
    the renderer (the GL renderer exports its internal APIs into the
    GLShader).
    
    There haven't been any complaints that I'm aware of since 4.14 was
    released where the default renderer does not support the nodes, so usage
    in public seems to be close to nonexistant.
    
    The 2 uses I know of were workarounds about missing features in GTK that
    have stopped since GTK now supports them:
    
    1. GStreamer used in to do premultiplication when the old GL renderer
       did not do so in hardware but on the CPU.
    2. Adwaita used it for masking before the mask node wa added in 4.10.
