This adds a bunch of snazz to the gltransitions demo. It is perhaps a bit overloaded now, but it demos everything that we can do. Changes: * The fire shader is now not a bin, it just renders an animating background with no textures involved. * The stacks don't all start on the same page. * The shaderbin passes the mouse coordinate to the shader. * The shaderbin allows specifying a "border" so that you can cause effects outside the bin child (something that is new to gtk4). * All the buttons and the stacks are now in shader-bins that runs a wobbly-widget effect based on the mouse position that wobbles outside the child allocation.
