Idea: gui/cursor #5756
Description
Many of our tools require the use of a keyboard cursor, but DF doesn't support it particularly well. I had an idea for an overlay that uses the mouse cursor to set df.global.cursor when clicked.
It could also have a button (hotkey Ctrl+C) to copy the selected position to the clipboard in the form x,y,z for pasting into commands. There could be a box selection mode to copy a pair of coordinates to the clipboard.
Somewhat related to #2665, but that's for using the keyboard to move the cursor. This tool could support it, but I'm uncertain if a gui window is desired for that purpose.
It could also sync with the adventure mode look cursor if that's active, which for some reason is separate from the global cursor.
