From 8c81b3fb8b9c857626c037fe0c95c5d48a3ca20f Mon Sep 17 00:00:00 2001 From: Pablo Dobarro Date: Sat, 26 Sep 2020 21:59:30 +0200 Subject: Sculpt: Line gestures and Mask Line tool This adds support for line gesture to SculptGestureContext and implements a Mask Line tool, which affects everything to the right of a plane defined by the straightline gesture. For this to work, a new WM_gesture_straightline_oneshot_modal is needed which only runs exec when the gesture is over. Added as experimental as it does not have icon.
