render: resize: copy styled underlines to temporary grid

Browse source 
When doing an interactive resize, we create a small grid copy of the
current viewport, and then do a non-reflow resize.

When the interactive resize is done, we do a proper reflow. This is
for performance reasons.

When creating the viewport copy, we also need to copy the styled
underlines. Otherwise, styled underlines will be rendered as plain
underlines *while resizing*.
