Floating groups can only be specified with left, top, height, width:

export interface Box {
    left: number;
    top: number;
    height: number;
    width: number;
}

It's useful in CSS to be able to "anchor"views to corners other than top left, e.g. using bottom and right attributes

export interface Box {
    left: number;
    right: number;
    top: number;
    bottom: number;
    height: number;
    width: number;
}

Would be super useful to expose this capability in dockview as it would allow floating groups that are:

• Fixed size, Top-left anchored 🟢
• Fixed size, Top-right anchored 🔴
• Variable width Top anchored 🔴
• Fixed size Bottom-left anchored 🔴
• Fixed size Bottom-right anchored 🔴
• Variable width Bottom anchored 🔴
• Variable height Left anchored 🔴
• Variable height Right anchored 🔴
• Variable height, Variable width 🔴

I could do it myself in JS with manual window size management above dockview, but it sucks

This is most useful for pre-defined views for end users, not sure how we could allow UI to let the user pick where to anchor their view when editing, but I don't think it's needed at first.
