/* When animating a cursor, we usually call drmModeSetCursor2 once per frame.
* Though, testing shows that we need to triple buffer the cursor buffer in
* order to avoid glitches when animating the cursor, at least when running on
* Intel. The reason for this might be (but is not confirmed to be) due to
* the user space gbm_bo cache, making us reuse and overwrite the kernel side
* buffer content before it was scanned out. To avoid this, we keep a user space
* reference to each buffer we set until at least one frame after it was drawn.
* In effect, this means we three active cursor gbm_bo's: one that that just has
* been set, one that was previously set and may or may not have been scanned
* out, and one pending that will be replaced if the cursor sprite changes.
