1. Use atomics and return exact cursor positions from egl_cursor_render to avoid race conditions between cursor render and update. 2. Instead of messing with lastCursorValid in various overlays, simply use the hasOverlay/hadOverlay logic for cursor damage. This simplifies the logic greatly. As a result, I believe all cursor-related artifacts are fixed. Note to reviewer: as atomic_init and atomic_store are implemented as macros, it is currently not possible to pass structs as compound literals due to the comma being interpreted as an argument separator by the preprocessor.
