Title: use column_stack to speed up gather_points

`gather_points` function in `lineplot` uses `transpose(array( (xs,ys) ))` instead of the much faster `column_stack( (xs,ys) )`.

There are a number of other places in the code where array() is also used, like in the render_hold functions, which presumably could also be sped up like this, but I haven't tried.
