Add a debug mode to the ui #39
Description
This should allow the user to create a togglable view that marks nodes they are interested in with a background.
This'll basically be a Vec<(ViewId, some-set-of-filters)> that, when enabled will be used after the state render and before the debug overlay render to patch nodes that match the filter.
Along with this, a togglable view to mark a node as a root and a compact-tree can be built from that and displayed to the user.
some-set-of-filters would be represented probably be either a struct of bools or bitflags.
What determines this is the following:
What should be markable?
- interactive
- hovered
- focus
- flex
- clipped?
- specific event interests?
