With HEAL armed the wheel was the brush's size and nothing else. A repair is
aimed at a detail — a scratch, a speck on a face — and the detail is usually
smaller than the photo, so the one gesture the stage uses to bring it closer was
the one gesture the brush had taken: a user could size the spot they were about
to lay and could not zoom the photo they were laying it on. The same layer took
the pointer the stage pans with, so a zoomed-in photo could not be moved out of
the way either, and it swallowed the double-click the img answers with. A tool
that covers the surface has to hand back the gestures it does not use.
The wheel over the brush is the stage's own now, exactly as it is everywhere
else in the app: one notch at the pointer, the point under the cursor held
still, the same arithmetic the wrap's listener has always used (lifted out of
that listener as zoomAt, so the two callers cannot drift). The brush's size —
the one knob this tool has — is that same wheel with a modifier held: Alt, or
Ctrl/Meta, which is also what a trackpad sends for a pinch, so pinching still
sizes the spot without reaching for a key. The photo can be moved out from under
the brush as well: the middle button, or the space bar held, drags the photo
while a tool is up, at a zoom, which is the only place a pan means anything —
the listener is on the layer, so the key is watched on the window and read from
a ref. A pan drag paints nothing, and the modifier wheel does not touch the
zoom: measured, 24.744px -> 29.6239px of brush across while the photo stayed at
1568px.
The × a chosen spot wears is now drawn for the screen rather than the layer: it
keeps 18px and a 5px gap at any zoom, scaled back out of the layer's own
transform. It was scaling with the photo — 18px of badge is 27.9px at ×1.52 —
and at that size its corner sat over the circle it belongs to, so a press meant
to take hold of a repair landed on the × and deleted it instead. 5px of daylight
at the fit and at ×1.52, measured both.
The histogram goes off the photo while a brush is up. It is a panel over the
photo's top-left corner with the pointer on it, and the corner is where a user
paints first: a drag under it painted nothing, and the wheel over it belonged to
the panel rather than to the photo. The crop frame already had it hidden for the
same reason.
ponytail: the pan is bound to the middle button and the space bar rather than to
a second pointer, so a trackpad-only user has the zoom (two fingers) and the
brush's own size (pinch) but no one-finger pan while a tool is up; a modifier
plus drag, or a small hand tool on the toolbar, is the upgrade path. The brush
size now lives behind a modifier that nothing on screen advertises — the chip's
percentage is the only hint — so a stepper in the brush chip is the next thing
to add if that turns out to be a wall. Double-click to zoom is deliberately not
wired up: the layer swallows the press, so the first half of the double-click
lays a spot, and a zoom that leaves a stray repair behind is worse than no
zoom. The middle-button pan only engages past the fit, where the drag is free
rather than a scroll, matching what the stage already did.
Verified: heal-zoom-drag-probe.cjs 28 PASS / 0 FAIL on :5199 and on :8090 after
deploy — the brush arms as a layer, the histogram is gone from the corner and
the circle follows the pointer there, the wheel zooms (1031px -> 1185px) and
leaves the brush its size (24.744px -> 24.744px), Alt+wheel sizes the brush
(24.744 -> 29.62) without moving the zoom, the modified wheel over the brush
sizes it and leaves the window's own frame alone (1440 CSS px, dpr 1, either side of the
notch, so the modified notch is not handed on to the browser's page zoom), a
plain drag paints 0 -> 7 spots, the
middle button moves the photo 215,34 -> 269,66 without painting, space+drag
moves it 269,66 -> 179,6 without painting, and taking hold of a repair moves it
from the centre, from 0.8 inside its edge and from its other side at both the
fit and ×1.52; the × has 5.0px of daylight and is 18px across at both zooms; 0
