}

One unit of cursor-callback work handed from the calloop thread to the wl-cursor worker. The calloop resolves everything renderer/surface-affine (SHM copies, dmabuf readbacks, hotspots); the worker does the PNG encode, the cache, and the GIL-bound Python call so none of that latency lands on the input/render thread. One channel keeps cursor updates ordered with callback (re)registration.

Variants

SetCallback(Py<PyAny>)

SetSize(i32)

Reload the worker’s theme handle at a new pixel size; later Named jobs render at it.

SetSizeCap(i32)

Cap the longest delivered cursor edge in pixels; larger sprites are downscaled with the hotspot. <= 0 delivers them uncapped.
