ssd: fix pixman error when SSD is created for tiny windows

set_squared_corners(false) was always called when titlebar is created.
However, set_squared_corners(false) sets the width of the titlebar
background buffer to (view width) - (corner radius), which causes pixman
errors due to the negative width set for titlebar background buffer when
the view is so small.
