gui_toolkit 0.82.0

Changed

• Middle-click autoscroll goes five times faster by default: up to 15000 px/s, reached 300 px from the anchor, the speed doubling every 60 px (DEFAULT_AUTOSCROLL): the curve Wren settled on. It was 2800 px/s at 420 px.
• A target_hz above the screen's rate is made: 120 on a 60 Hz screen is up to 120 frames a second while something moves (none at rest), each on its slot, none waiting for the screen, shown at once (Cadence_Plan.above): it stayed at the screen's rate. The screen shows the newest: not smoother, but each refresh has fresher input.
