Getting the cursor image from the cursor theme is unfortunately not straight forward. We have three different libraries and all have drawbacks: * XCursor - we just kicked it out * xcb-util/cursor - only provides xcb_cursor_t, so a dependency on X * wayland-cursor - only a client side API The picked solution is using wayland-cursor. It provides the cursor in a wl_buffer. Unfortunately the client side API does not easily allow to a) read it back b) init without a wl_shm_pool Thus we need to work this around: * create an internal connection * get a ShmPool on it * init WaylandCursorTheme with this ShmPool * get the cursor wl_buffer from the theme * trigger a roundtrip * get the corresponding BufferInterface for the buffer * set the content as the software cursor
