26b4776394 fix wrong bucket calculation for western hemisphere, close to poles, full-degree-longitude calculations. 
set_bucket computed false left border, if the span was greater than 1, longitudes were less than zero
and longitudes were within SG_EPSILON on a full degree. Example: -179.0, +87.5 returned -176, 87
but should return -180, 87.

679db5a22b The chunked stuff is no longer needed for the ground tiles. 
... I (Mathias Froehlich), believe that it is more performant (for the GPU) to
build the biggest indexed sets possible at the expense of tight culling.
I (Mathias Froehlich) also know that the CPU is more performant on smaller chunks
building the old flat groundcache on such tiles. :)
So this code *was* to balance these two contrary requirements to some degree.

Now we have optimized datastructures for drawing and differently optimized
datastructures for intersection tests.

0e35168bdb Also align the ocean tiles with some horizontal axis. 
This way the bounding boxes for this geometry is slightly smaller.
Helps ground intersection stuff to avoid the ocean triangles earlier.
