Before this commit, on creation, `SubWindow` gets resized to exactly the children's `sizeHint`. This makes the child too small, since the `SubWindow` already contains a title bar and borders. With this commit, the `SubWindow` is calculated such that after rendering, the child window gets exactly the `size` that its `sizeHint` has previously suggested. Most of LMMS widgets are not resizable, but the Lv2 help window is a good example to test this out. The help windows now in most cases contain enough space to fit the help text. In some cases, it still does not fit, though debug prints show that the `size` matches the `sizeHint`.
