Performance

Full renders are faster on Paper, and on Fabric and NeoForge with Moonrise. In our benchmark, a full render took 41.50 s instead of 64.72 s, a 1.56× speedup (Ryzen 9 5950X, 1,495,729 chunks). (#615, #616)

• Decode saved chunk sections directly instead of through Minecraft's codecs (#615)
• Remove lock contention when writing rendered pixels (#616)

Without Moonrise, render speed is limited by Minecraft's own chunk I/O, so these changes don't make renders faster there. For the fastest renders on Fabric and NeoForge, install Moonrise.

Fixed

• Fabric, NeoForge and Sponge without Moonrise: fix renders stalling the server thread while waiting for chunks to be read from disk, causing lag during renders. Present since squaremap 1.1.0. Render speed is unchanged
