The shadow outline of the player's hotbar is too prominent, leading to item textures appearing to clip over the hotbar, when they actually occupy an expected resolution of space (16x16, and not 17x17 for example). This affects a many multitude of items.

Steps to Reproduce:

1. Set GUI scale to as high/big as it will go
2. Place one of the following items into the hotbar
   

Expected & Observed Results:

- The items will appear to clip over the hotbar.
- They would not appear to clip, as they in actuality do not.

Notes:

1. This is not art feedback, as this has specifically caused confusion as to whether or not items are clipping elements of the player's UI. This leads to item textures being changed, when they do not need to (see MC-142385 for the campfire).
2. Considering the core issue here is the hotbar's texture and not all the different textures of affected items, I would ultimately suggest that the linked issues be forward resolved into this one (whether that be duplicating, or whatever else), and that the item textures not have any changes made to them. Reason being, there are many affected items by this (see 'ApplicableItems.png'), and altering each item's texture rather than the texture causing this problem is likely not efficient, or ideal.
