PLAYER_MAX_BREATH_DEFAULT was earlier set to 11, so that 10 bubbles are shown before the breath bar disappears.
Now, PLAYER_MAX_BREATH_DEFAULT is set to 10, and the breath_bar scaling code in builtin has been tweaked to show all 10 bubbles before hiding the breath_bar
* Respect object property hp_max field for players
This allows modders to configure the maximal HP per player
* Statbars: Downscale bar to full 20 HP when exceeding this value
Add default max HP for players and breath constants to builtin
Document the constants
* Rename PLAYER_MAX_HP -> PLAYER_MAX_HP_DEFAULT
Add 'core.LIGHT_MAX = 14' to builtin/game/constants.lua with the intention
to replace misplaced 'default.LIGHT_MAX = 14' in Minetest Game.
Add comment in light.h requiring the constant be changed in both places.
Add lighting bug warning to note in lua_api.txt.
There are hundreds of mod uses of 15 which causes a lighting bug.
