panX/panY now represent 0..1 fractions of the pannable range rather
than absolute image positions, so the slider's full travel always
covers edge-to-edge regardless of zoom level. Pan Y is inverted so
sliding right moves the view up. Updated both the editor canvas and
core/raster.js export so they stay in sync.
