Free Placement

First Release.

• Place blocks at half-block or quarter-block positions: G cycles Half / Quarter / Normal grid.
• Offset blocks keep their real shape: you walk on them, bump into them, click and break them where you see them.
• Chests, furnaces, hoppers, redstone, doors, beds, torches, signs, rails (minecarts ride them), scaffolding, trapdoors and much more work off the grid.
• Fences, walls, panes and gates connect to their neighbours; chests still pair up.
• A see-through preview shows where the block will land (H hides it); a small hint line above the hotbar fades after a few seconds (J hides it).
• Offset roofs block the sun; blocks placed in water stay waterlogged.
• Works with Sodium and Iris.
• Known issues: redstone power still follows the normal grid, a few faces can look too dark, lava isn't kept around offset blocks yet.
• Releasing as full first release but project likely has issues to be worked out.
