From 5794a223ce9c22cee11a395bd0aa9477939becde Mon Sep 17 00:00:00 2001 From: Ronan Pigott Date: Wed, 16 Nov 2022 15:50:34 -0700 Subject: view: associate launch contexts with views Views now maintain a reference to a launch context which, as a last resort, is populated at map time with a context associated with its pid. This opens the possibility of populating it before map via another source, e.g. xdga-tokens or configuration.
