Add full handle/grip assembly to the bottom of SSD window frames, following the Openbox themerc specification for geometry and theming. Theme parsing: - Parse window.handle.width (handle bar height, default 6) - Parse window.grip.width (corner grip width, default 20) - Parse window.[active|inactive].handle.bg with Solid/Gradient support - Parse window.[active|inactive].grip.bg (inherits from handle if unset) - Pre-render 1px-wide fill buffers and cairo patterns for handle/grip Scene graph (new ssd-handle.c): - Handle assembly replaces bottom border when active, with its own left/right/top borders and three-segment bottom border - Grips at left/right corners for diagonal resize (sw/se-resize) - Center handle for vertical resize (s-resize) - Vertical separator lines between grips and handle using border color - Per Openbox spec, handle_width is content-only height with borders drawn around it (total assembly height = 2*border_width + handle_width) Interactive visual states (grips only): - Hover: 20% black overlay on grip content area - Pressed: 40% black overlay with 1px inset shadow (dark top/left, light bottom/right) for a pushed-in 3D effect - Dragging: 20% overlay with inset shadow maintained - Global hover tracking (server.hovered_handle_ssd/element) ensures proper cleanup when cursor moves across views or to desktop Decoration toggle cycle (ToggleDecorations action): - New LAB_SSD_MODE_BORDER_HANDLE between BORDER and FULL - keepBorder=true: full -> border+handle -> border -> none -> full - keepBorder=false: full -> none -> full (unchanged) Node types and input: - New LAB_NODE_HANDLE, LAB_NODE_GRIP_LEFT, LAB_NODE_GRIP_RIGHT - Integrated into LAB_NODE_BORDER/BORDER_BOTTOM containment so existing Border context mousebinds (Resize) work automatically - Handle/grip descriptors resolved directly in get_cursor_context() bypassing ssd_get_resizing_type() for precise cursor shapes Visibility rules: - Hidden when maximized, shaded, or handle_width is 0 - Hidden in LAB_SSD_MODE_BORDER and LAB_SSD_MODE_NONE states - Bottom border in ssd-border.c disabled when handle is active Documentation: - labwc-theme.5.scd: document all handle/grip theme properties - labwc-actions.5.scd: update ToggleDecorations to 4-state cycle - docs/themerc: add handle/grip default values
