Module driving 

Driving the kernel the way a front end does — batches of events on a 60 Hz clock over a fixed viewport — for the suites and benches above it.

The camera rests at unity with the viewport at the origin, so screen and world agree until something moves the camera.

Structs

SettledGrid

The n×n autogen grid, settled — every wire routed and its corners written. Settling is the slow part, so it is done once and sessions are seeded from it.

Constants

FRAME

One 60 Hz frame, so the easing table advances the way it does live.

VIEWPORT

The canvas every batch reports.

Functions

at

The tick for millis into the session.

batch

A batch as a front end sends one: what time it is and how big the canvas is, in front of whatever happened.

batch_in

The same, from a canvas of another size.

blocks

Every block of the viewed document, in id order.

down

The primary button pressed at pos.

moved

The pointer over the canvas, here.

up

The primary button released at pos.
