PackedTextureTile

ceramic.TextureTile → ceramic._TextureTilePacker.PackedTextureTile (private class)

Internal texture tile implementation with grid allocation metadata.

PackedTextureTile extends TextureTile with additional information about its position and size within the packer's grid system. This allows the packer to track which grid cells are occupied and properly release them when the tile is no longer needed.

See: TextureTilePacker The main packer that manages these tiles
