Set the main window's dock-widget corners when locking a docker
Set corners in favor of the docker being locked, but only if the adjacent dock-widget area is empty, or if it doesn't alter the current layout.
Test Plan
- Place a docker in the bottom dock-widget area. You'll notice that it spans the entire width of Krita's window, and in the process it also squishes the left and right dock-widget areas.
- Float the docker that you just docked, find a different docker that resides in either the left or right dock-widget area, and lock it.
- Place the floating docker back into the bottom dock-widget area. You'll see that it no longer spans the window's entire width and instead stops at the dock-widget area of the locked docker.
I made a video of a test case scenario to help better illustrate how this feature may be useful.
