New Map Markers

So obviously we need more features of Java maps and Bedrock maps exchanged, like regular and locator, and when you go off the map in Java your icon becomes a square, into Bedrock. And banner markers. But I think we can have something along the lines of a map canvas, where you can draw a line on a map to show a border between 2 areas of your world. This could be used in map creation, if you want to show a story on the map to make adventuring a bit more interesting.
