Because I wasn't happy with the uphill flowing water, I continued with researching better ways to do it. I ended with some new approaches but still not good enough to implement it in the game. So I removed the uphill flowing water and smooth out the wall of the rivers. I also released the next version V1.10 (Terrain-system-update).

Normally I wanted to continue with improving the caves next, but this will be the same mathematically research pain. So I switch the plan and add more survival mechanics, before I improve the caves.

Change log:
changes:
- game and landscape tester: terrain generation
- game: slope next to rivers instead of river walls
- game and landscape tester: terrain creation to fix the issue, that objects, like grass, were sometimes lined up
- landscape tester: increased performance on „count world objects“ (all logical kernels are now used)
- game: increased performance of drawing a map of a planet

bug fixes (game):
- objects, like houses or cave entries, were sometimes in the air or in the ground, because of a wrong terrain height calculation
- game crashed, when player got close to the border of the planet
- flashlight shadow issue (shadow of the players head was directly in the middle of the view)
