Version 3.1

• Optimized memory usage and load speeds in texture/shape picker
• Refactored all of the UI with ImGUI; scroll views and text boxes function better.
• Entity configuration UI enhanced; removing properties more ergonomic, don't need to press 'place' button to confirm changes.
• Entities now support model & billboard display modes
• Enhanced some textures, added new textures, added textures to be used as sprite billboards.
• New settings for default shape & texture, background color
• .te3 file format now saves editor camera position for convenience
• .te3 format now uses run-length encoding on blank tiles, dramatically reducing file size
• Export now supports .glb files
• Exported model can optionally cull unnecessary faces between tiles
• When exporting with separate nodes for each texture, texture names are now formatted as relative to the model file, and the special characters in the file path are replaced with '_' to be compatible with Godot.
• Errors fixed with exported .gltf/.glb scenes
• New tile shapes
• Built-in support for importing Total Invasion II maps (for my own convenience)
