A GUI-side view onto one pipe's currently published backbuffer: wraps the pipe cache's own memory, never an independent copy (pixelpipe_hb.c owns the keepalive ref). Callers declare and own their own instance(s) - darkroom keeps one for dev->pipe and one for dev->preview_pipe, Studio Capture owns exactly one, for its main pipe only. Initialize .hash to DT_PIXELPIPE_CACHE_HASH_INVALID before first use - a zero-initialized (calloc'd) instance looks like a valid hash of 0, not the sentinel.
Draw the ISO 12646 white surround rectangle around a width x height image with border px margin.

Draw the "soft proof" / "gamut check" text overlay in the bottom-left corner when darktable.color_profiles->mode is not DT_PROFILE_NORMAL; a no-op otherwise.

Pick the background color for the center view: ISO 12646's fixed L=50 grey when enabled, the user's "display/brightness" conf otherwise.

(Re)bind locked to pipe's currently published backbuffer if it is newer/still valid. wait and wait_owner_tag are the caller's own dt_dev_pixelpipe_cache_wait_t instance and a short static debug label (e.g. "darkroom-main", "studio-capture-main"). keep_previous_on_fail: on a miss, keep whatever locked already held instead of dropping it.

Convenience for a caller that only wants the main (FULL) pipe's tier, with no separate preview-pipe substitution: lock + render dev->pipe in one call. This is what Studio Capture uses; darkroom's own multi-tier fallback cascade calls dt_dev_lock_pipe_surface()/dt_dev_render_locked_surface() directly instead.

| void dt_dev_release_locked_surface | ( | dt_dev_locked_surface_t * | locked | ) |
Drop everything locked references. Does not touch the pipe cache entry itself (pixelpipe_hb.c owns it). Callers MUST call this, on every instance they own, before their dev's pipeline nodes/backbufs are torn down.

Paint locked's surface into cr, centered in a width x height widget with border px margin and bg_color background; also draws the ISO 12646 white surround iff dev->iso_12646.enabled. Pure paint - call dt_dev_lock_pipe_surface() first.
