Port some of the openGL effects plugins to vulkan

Currently vulkan rendered is incompatible with (almost - except of simplest animations) all the effects. that actually were an important feature of Wayfire making it something special in the long row of wayland compositors. With vulkan its all gone and there is no plugins with vulkan calls and no referrence to look at how to proceed with vulkan shaders. I saw one exaple by killown starting vulkan shaders - but that one was just rendering to internal bitmap, so still a mistery how to do something like flame of wobbly when shaders results need to be somehow applied to window rendering.

Review the existing OpenGL effects plugins and the referenced killown Vulkan-shader example, which currently only renders to an internal bitmap. Determine how shader results must be applied to window rendering, then port selected effects so they work with the Vulkan renderer and verify that their animations render correctly.
