 ### WINGs Porting Strategy

+- [x] **DND subsystem** (`dragsource.c` + `dragdestination.c` + `dragcommon.c`, 2437 LOC,
    98 calls) — **done**. Compositor-internal DND fully functional (drag image, cursor feedback,
    hit-testing via W_FindViewAtPoint, modal drag loop in wl_drag_begin). Cross-client DND
    (wl_data_device) has basic wiring — needs MIME type → WINGs type routing to complete.
 
-2. **`wcolorpanel.c`** (3556 LOC, 89 calls) — route pixmap operations through
-   `W_RenderBackend`, pointer grabs through `W_ViewBackend`.
+- [x] **`wcolorpanel.c`** (3556 LOC, 89 calls) — **done**. Split into three files:
+   `wcolorpanel.c` (backend-neutral, 2997 lines), `wcolorpanel_x11.c` (X11 magnifying glass,
+   601 lines), `wcolorpanel_wl.c` (Wayland stub). Magnify button shows "not available"
+   dialog on Wayland. All 89 X11 calls isolated to `wcolorpanel_x11.c`.
 
 3. **`wwindow.c` + `widgets.c`** (1849 LOC, 76 calls) — window property management
    needs backend dispatch (ICCCM is X11-only; Wayland properties differ).
