apps/client/src/renderer/gallery-camera

The galleries' free camera (?kit-gallery, ?vehicle-gallery, ?anim-gallery): an orbit camera over the ground that goes anywhere, since a gallery may hold hundreds of things, some a few metres across and some a few kilometres.

• W A S D or the arrow keys pan over the ground, the way the view faces, faster the higher it is; Shift pans four times as fast.
• The wheel, or Q and E, zooms in and out.
• The left button dragged orbits and tilts; the right button dragged pans, the ground following the mouse however high the camera is.
• 1–3 set the height over where it looks (the gallery's own three); F goes back to what the gallery first looked at (its focus).
• Its speed (from a quarter to eight times: + doubles it, - halves it, the panel's slider sets it, gallery-ui.ts) scales the panning, the zoom and the wheel; each gallery keeps its own in the browser (loadSpeed), so a big one stays fast.

The keys are read on the window, so the canvas need not have the focus (it takes it anyway), except while something is typed in a field (typingIn): a search never moves the camera.
