The bug

When breaking a placed pointed dripstone, the cracking texture is not locked to the same grid as the block's own texture, resulting in the cracking texture being misaligned.

THIS IS A DIFFERENT BUG FROM MC-142156 - while MC-142156 makes this effect clearer to see, that bug is a fundamentally different problem (it concerns cracks appearing on transparent surfaces, whereas this ticket concerns cracks not being aligned correctly to the pixel grid) and fixing one will not fix the other.

How to reproduce

1. Place pointed dripstone
2. Start punching it in Survival
3. Pay close attention

Expected results

The cracking animation would be aligned to the same pixel grid as the pointed dripstone texture.

Actual results

There is a misalignment on the horizontal axes.

MC-142156 allows us to see a secondary side-effect of this issue: if we continue to punch the block until it breaks, the cracking animation eventually appears cut-off on one side.

How to fix

It may be possible to fix this issue by only allowing blocks with random offsets, such as pointed dripstone, to only be offset by sixteenths of a block.
