Tiled Terminal Widgets

[marcxjo]

I love Tilix, but I want something a bit more basic. (That's more or less the reason I created Stulto.)

On the other hand, I also have minor gripes with the implementation of tiling in Tilix. Ideally, we don't want to have to depend on GtkPaned to accomplish tiling; we want a widget type that we can predictably resize on-demand, and to which we can add an arbitrary number of tiled child widgets. We also don't want to have to make assumptions about the orientation of widgets upfront.

Under the hood, this'll probably be somewhat similar to Tilix, since we'll probably end up depending on GList to track the widgets' lineage, but ideally, we'll handle resizing, inserting, removing, and fake drawing separators manually (as opposed to depending on existing specialized container types). Ideally, under the hood we'll actually be implementing a generic GtkTiled, but that may turn out to be impractical.
