Make wayland load cursors on demand Copy just enough of libwayland-cursor to make our own loading. This lets us drop the dependency on libwayland-cursor, and changes the startup cost for cursor theme loading from 25ms to 0.1ms. At the same time, simplify the handling of scaled cursors - instead of creating an array of theme objects, just make a single theme object provide all scaled cursor sizes.

gdk: Add Cairo context implementations for all backends And make the GdkCairoContext as abstract. The idea of this and thje following commits is to get rid of all Cairo code in gdksurface.c (and $backend/gdksurface-$backend.c) by moving that code into the Cairo context files. In particular, the GdkSurfaceClass.begin_frame/end_frame() functions (which are currently exclusively used by the Cairo code should end up being moved to GdkDrawContextClass.begin/end_frame(). This has multiple benefits: 1. It unifies code between the different drawing contexts. GL lives in GLContext, Vulkan in VulkanContext and Cairo in CairoContext. In turn, this makes it way easier to reason about what's going on in surface-specific code. Currently pretty much all backends do things wrong when they want to sync to drawing or to the frame clock. 2. It makes the API of GdkSurface smaller. No drawing code (apart from creating the contexts) needs to remain. 3. It confines Cairo to the Drawcontext, thereby making it way more obvious when backends are still using it in situations where it may now conflict with OpenGL (like when doing the dnd failed animation or in the APIs that I'm removing in this branch). 4. We have 2 very different types of Cairo contexts: The X/win32 model, where we have a natively supported Cairo backend but do double buffering ourselves and use similar surfaces and the Wayland/Broadway model where we use image surfaces without any Cairo backend support and have to submit the buffers manually. By not sharing code between those 2 versions, we can make the actual code way smaller. We also get around the need to create 1x1 image surfaces in the Wayland backend where we pretend there's a native Cairo surface.

wayland: Add primary clipboard subclass I decided to put this in a custom subclass, because then I could keep the whole gtk primary protocol self-contained. The other option would have been reusing GdkWaylandClipboard, but that didn't seem worth it, especially because that code needs to interact with the DND machinery, while the primary doesn't.

wayland: Add support for xdg-output Previously, the GDK backend for Wayland would deduce the logical size of the monitors from the wl_output size and scale. With the addition of fractional scaling which advertises a larger scale value and then scale down the client surface, the computed logical size of the monitors in GDK would be wrong and confuse applications which insist on using the monitor size and position (like Firefox). The xdg-output protocol aims at describing outputs in a way which is more in line with the concept of an output on desktop oriented systems by presenting the outputs using their logical size and position appropriately transformed. Add support for the optional xdg-output protocol so that the size and position of the monitors as reported by GDK is correct even when using fractional scaling.
