* Reorganize MapEngine
This is already turning into a mess...
* Map engine selects tile index to use
Still very ugly
* Fix subtile flag combination
* Prepare randomly generated base tiles
* Restore collision viewer
* Movement works again, searches for straight paths
Paths are now d2vector slices
* Fix LOS calculation
* Fix test (I think)
* camera offset for ui panels :
added maprenderer viewport to be aligned left or right
calling alignement on keyPress in game_controls
* check if already aligned
* fix bugs
-forgot to assign alignement
-defaultScreenRect instead of screenRect because of issue mentionned in original comment
* remove config.json and replace go.mod line
* removing duplicate import of d2common
replacing all dh to d2common
* remove useless breaks from switch statement
* better range when value unused + prettying import
* item_affix rewrite
using return values instead of pointer references in arguments
* ebiten deprecated calls
* small fixes
* Switch to a 2d array for looking up subtile flags
Also fix up the walkableArea generation
* Check correct tiletype for walls
And fix the subtile tooltip text.
