Subject: [PATCH] Fix menu title bar: implement frame_buf resize in
 window_resize
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The menu frame was created at 1x1 and resized via wFrameWindowResize
which calls window_resize. But wl_window_resize didn't handle
frame_bufs — it only handled toplevel views. Now it reallocates the
pixman image when dimensions change, so the frame has the correct
size when wl_frame_paint renders the title bar.
