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:
        Affected Block Part Affected  Notes
        Banner  Entire Block Affected 'wall' variant too
        Sign Entire Block Affects all rotations
        Hanging Sign Chains  
        Wall Hanging Sign Chains & Top/Bottom
        when rotated
        Chains only affected when
        attached: false
        Chains Entire Block  
        Ender Dragon Head Entire Block Texture is not 16x16
        in resolution, affecting
        alignment
        Lectern Topmost Cube Also affects inserted book
        Skull / Head Entire Block Must be rotated
        Dripstone Entire Block Tracked in MC-256392
        Bamboo Stalk Tracked in MC-256390
      2. Mine the block long enough to see the cracks, following any notes listed above.

      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.

      Notes:

      1. Causes MC-256392 MC-256390 (The triage state of the two listed issues indicate that block breaking animation alignment is seen as a valid issue)
      2. Related to MC-183923 MC-212087 MC-142156 MC-167836 MC-269348
      3. If any affected blocks are missing, comment and I will add them to the table.
