First: disable d'n'd events by default; most apps don't need these at all, and if an app doesn't explicitly handle these, each drop on the window will cause a memory leak if the events are enabled. This follows the guidelines we have for SDL_TEXTINPUT events already. Second: when events are enabled or disabled, signal the video layer, as it might be able to inform the OS, causing UI changes or optimizations (for example, dropping a file icon on a Cocoa app that isn't accepting drops will cause macOS to show a rejection animation instead of the drop operation just vanishing into the ether, X11 might show a different cursor when dragging onto an accepting window, etc). Third: fill in the drop event details in the test library and enable the events in testwm.c for making sure this all works as expected.
