#' Cartesian coordinates per facet-panel

#' A 'panel_limits' data frame may contain:

Clipboard selection over remote (ssh) and optionally multi-plexed (tmux) connections. This is primarily from a windows machine using git-for-windows, mintty, and tmux remotely. Untested otherwise.

Other (non-Windows) solutions/recommendations include xclip on the remote end; these will not work unless there is an X-windows server running on the local (Windows) machine.

The remainder is effectively the results of my trial-and-error process.

mintty and OSC-52

Instead, this uses OSC-52 escape sequences. Because they can be considered a security risk (the remote end might be able to see the local end's clipboard values arbitrarily), the capability is disabled by default.
