Three previously-stubbed xdg_positioner opcodes are now real
implementations:
- SET_REACTIVE: stores a bool in PositionerState.reactive. Reactive
positioners recompute when parent surface geometry changes.
Cross-referenced with wlroots xdg-positioner.c.
- SET_PARENT_SIZE: stores the (w, h) parent rectangle in
PositionerState.parent_size. Used when no parent_configure
is set.
- SET_PARENT_CONFIGURE: stores the u32 serial in
PositionerState.parent_configure. This ties the positioner
to a specific parent xdg_surface.configure event.
The PositionerState struct gained three new fields:
reactive: Option<bool>
parent_size: Option<(i32, i32)>
parent_configure: Option<u32>
The old catch-all sed pattern that discarded all three opcodes as
a single empty match arm has been replaced with three explicit
arms. Each arm validates payload length before reading.
