Make map drawing dynamic

[tyra314]

Idea from Discord

*Drawing map view is how much blocks is filled in your map
First idea was that if you are standing at a field of flat level of about 100 blocks radius your drawing map view is about 10 blocks radius but if you standing on a mountain your flat level is 10 or less blocks and your drawing map view is about 100 blocks.
This way you can make that if you stand an a mountain and see the ground below you. Your map will eventually fill in a big chunk of area over a certain time, but if you are on ground level and you cant see that much. You only fill a small area but it instantly appears on the map.

Expanding on the idea:

• let it depend on the position
• let it depend on movement speed
• let it depend on the actual direction players are looking
• looking through the telescope improves drawing distance
