It's just the default, individual games should be able to override it, and

Add tiny Y offset in collisionMoveSimple() to tweak performance
Another small general problem: the player is always standing exactly on the
bondary between 2 nodes e.g. Y=1.5 is exactly between nodes Y=1 and Y=2.
floatToInt() and myround() will round +/-n.5 always 'outwards' to +/-(n+1),
which means they behave differently depending on where you are: they round
upwards above sea level and downwards when underground. This inconsistency
comes from the way the coordinates are calculated, independent of the
specific C++ code.
The result is a tiny bit of lost performance when moving underground,
because 1 node level more than necessary is checked for collisions. This can
be amended by adding a tiny offset to minpos_f.Y, like @paramat suggested.
This is not an elegant solution, but still better than wasting CPU.

Fix player coordinate rounding in collisionMoveSimple() (#6197)
To determine the area (nodes) where a player movement took place
collisionMoveSimple() first took the old/new player coordinates and rounded
them to integers, then added the player character's collision box and
implicitely rounded the result. This has 2 problems:
Rounding the position and the box seperately, then adding the resulting
integers means you get twice the rounding error. And implicit rounding
always rounds towards 0.0, unlike floatToInt(), which rounds towards the
closest integer.
Previous (simplified) behavior: round(pos)+(int)box, for example player at
Y=0.9, body is 1.75m high: round(0.9)+(int)1.75 = 1+1 = 2.
==> A character's height of 1.75m always got rounded down to 1m, its width
of +/-0.3 even became 0.
Fixed by adding the floats first, then rounding properly: round(pos+box) =
round(0.9+1.75) = round(2.65) = 3.

The getBackgroundBrightness() function detects darkness in the view direction
to decide when to make the skybox dark. The volume checked was too narrow and
missed the left and right edges of the view, too easily causing a dark skybox.
Widen the checked volume to match a FOV of 72 degrees and a 16:9 aspect ratio
game window.

compressZlib: don't use a SharedBuffer but a raw u8 * pointer
Remove usage of the SharedBuffer in zlib compression which has two problems:
* We copied the whole memory block to compress it (not good with mapblocks)
* We copied sometimes strings to SharedBuffer to SharedBuffer (2nd time)
Use this method in MapNode::serializeBulk + optimize serialization but merging 3 identical loops in a single loop

Massive performance improvement on correctBlockNodeIds
correctBlockNodeIds does 2 lookups for each loaded node, one to translate DB ID to name and a second to translate name to real ID. Name to real ID is very consumming if done on every node. As mapblocks are in most cases composed of many identical adjacent nodes, cache previous source and destination id and use them on the next node to prevent any lookup on those maps.
This reduce the function load from 15% of my CPU usage to ~0.7%, on the test, calls was reduced from 2.5M lookups to 42k lookups, it's a huge performance gain
