P0-B7: Part 1354: Debugging, Improvements

I am continuing to work on debugging and playtesting the game.

I have fixed an issue with the grass rendering system which causes the grass to render more than once on the same area of ground, significantly decreasing performance.

This was caused by higher level terrain chunks still having their grass rendering when the chunk itself was paged out, in some cases.

This is now fixed.

I have fixed some issues with the scale of ground cover objects. Some objects, like trees, should have a semi-random scale, so that they don’t all look the same. However, other objects, such as man-made objects like cabins, escape pods, etc, should have a fixed scale otherwise they don’t look right.

I also made some minor improvements to the life simulation variables.
