Graphics

• Improved the blueprint grid visualisation, so it shows a rectangle instead of just the corners.
• Added blueprint grid visualisation when building in the world.

Bugfixes

• Fixed cleaning ghost cursor. more
• Fixed crash when clicking a blueprint book upgrade slot with an upgrade planner in hand.
• Fixed navigating in a blueprint book item when opened directly from a quickbar. more
• Fixed that it was possible to put book into itself using hand->swap and clean cursor.
• Fixed that the hand functionality didn't work properly for gun and ammo and gave misleading error messages in some cases.
• Fixed "slice" property of animation definition was interpreted as dicing parameter, possibly causing large memory allocations. more
• Fixed that grabbing gun/ammo, swapping it with some other item in the inventory and pressing Q, gave a message of inventory full, instead of the item in cursor not being returnable to the hand location
• Fixed that Internal inventory stack transfer messages weren't specific enough, or not present at all.

Modding

• Renamed sprite and animation properties for sprite dicing from "slice", "slice_x" and "slice_y" to "dice", "dice_x" and "dice_y", because "slice" collided with property of rotated animation definition used for defining spritesheet sliced into multiple files. Sprite dicing is a technique of chopping large sprite into smaller ones to improve packing in sprite atlas.

Scripting

• Fixed a typo (per vs pre) in the on_pre_permission_group_deleted event name.
