// This structure is stored in shared memory that's shared between the browser
// which does the hardware polling, and the consumers of the data,
// i.e. the renderers. The performance characteristics are that
// we want low latency (so would like to avoid explicit communication via IPC
// between producer and consumer) and relatively large data size.
// Writer and reader operate on the same buffer assuming contention is low, and
// contention is detected by using the associated SeqLock.
