Canonical view grid

A dock_grid is a view's geometry in our compact, dockView-independent form – nested splits and tab groups with sizes normalised to 0-1 ratios and no volatile ids, so two casts of the same layout compare identical(). It is authored with dock_grid() and produced by as_dock_grid(), which casts another dock_grid (identity) or a dock_layout (dockView's client echo) into it and is idempotent. is_dock_grid() is the class check; validate_dock_grid() returns its input and errors on a malformed or non-canonical grid.

Usage

as_dock_grid(x, ...)

is_dock_grid(x)

validate_dock_grid(x)
