# What leaks from stack to heap?

go build -gcflags=-m=2 . 2>&1 | less

# Changes:

* RenderF
    This doesn't need to return .Bytes(), we can use the output (*bytes.Buffer)
    This is Redundant.

* Panel
    Change []Line to []*Line
    Otherwise adding to Lines is a Copy/Makes more garbage. (!)

* Line
    I'd like NewLine to take (narg... any), to init:
        Text
        RenderF
        UpdateF
        Width
        DefaultColor (the 2nd "text" item)
    And have NewLine return *Line.
