Block breaking animation does not account for geometry which isn't aligned within the 16x16 block space resolution

If the player breaks a block which is not within the 16x16 block resolution, or has slanted/shifted model-parts, the block break animation will not display properly. Often, the animation will be stretched, misaligned, or too large/small.

This issue is not MC-142156, though it is directly related. This issue specifically pertains to alignment, not visibility. This issue is also not MC-167836, as that issue includes full-cuboid blocks and applies across all blocks generally. It does go hand-in-hand with this issue though.

The core of this issue is that the breaking animation is always trying to center itself inside the 16x16 pixel space of a block, with a scale of 1. This works fine when blocks are within that space (like a full block, or a block which aligns on that grid), but when a block goes outside that alignment in any way, the issue arises.

Steps to Reproduce:

  1. Place down any of the listed blocks in the table below

  2. Mine the block and observe the block breaking animation

Expected & Observed Results:

❌ - All blocks listed above have incorrectly displayed block breaking animations on at least one cube of the block, or more.
✔ - The block break animation would properly scale, rotate, and move as appropriate for the block currently being broken. If the break animation is not intended to be dynamic, it would at least be properly aligned vertically and horizontally for each case.
