dragScalar sizes the 'input box' too greedily

[zeroeightysix]

When indented in tree nodes, dragScalar widgets will use too much space for the input box, often causing the label to be unreadable:

Making the window much larger will reveal the label, slowly:

Better would be for the input box to size with the window accordingly, and always reserve enough space for the label. This behaviour works fine when not indented, as seen in the demo window:

To reproduce:

dsl.treeNode("a") {
    dsl.treeNode("b") {
        dsl.treeNode("c") {
            dragInt("overly long label", ::c)
        }
    }
}

This still matches the native behaviour, I'm gonna open an issue over there probably
