batch_ops

What a Canvas batch records: the op, the batch holding them, and the constructors for the ops with no geometry to gather.

These are the recording half of batching. They are plain data – scalars and side lists, no Canvas – so that recording an op is an append and a batch of thousands of markers costs a few amortized growths rather than an allocation each. canvas.batch is the other half: it walks these per row band and draws them.

They live in their own module because both halves need them and neither owns them: canvas.buffer records, canvas.batch renders, and canvas.shapes reaches for the op constructors when a primitive records itself instead of drawing.
