[x] collision primitives (circles, rects).\n  - [x] collision meshes built from primitives (rigid and soft).\n  - [x] configurable friction, gravity, drag, and restitution.\n  - [x] super-sampling.\n  - [ ] (good) multithreading.\n  - [x] Cell list collision detection.\n  - [ ] Quad tree collision detection.\n  - [x] Object-object and object-world collisions.\n  - [ ] collision islands and other optimisations.\n- Rendering (provided by jGL, Vulkan is a WIP):\n  - [x] OpenGL.\n  - [ ] Vulkan.\n  - [x] sprites (atlasing, and animateable atlases).\n  - [x] collision primitives (circles/rects).\n  - [x] Freetype fonts.\n  - [ ] shapes (it is in jGL).\n  - [ ] lightmaps and shadows.\n  - [x] msaa.\n  - [ ] particle effects (it is in jGL).\n  - [x] texture management.\n  - [ ] (compressed) texture asset packs.\n  - [ ] Engine UI (Dear ImGui).\n- Window management:\n  - [x] Single window creation.\n  - [ ] Multi-window.\n  - [x] Key and mouse events.\n  - [x] Frame limiting.\n  - [ ] Snapping and resizing.\n  - [x] Screenspace bbs. \n- Worlds:\n  - [x] Perlin (marching squares).\n  - [x] Tile maps.\n  - [x] object-world collisions.\n  - [ ] editable.\n  - [x] saveable.\n  - [ ] tile textures.\n- Lua console\n  - [x] ECS bindings (object management).\n  - [x] Compressed script asset archive support.\n  - [ ] Live in game console \n- Cross platform:\n  - [x] Linux.\n  - [x] Windows.\n  - [x] macOS.\n  - [x] Android.\n  - [ ] IOS (mostly held up by jGL rendering).\n- Tooling\n - [x] mesh editor.\n - [x] Lua script packer.\n - [ ] World editor.\n - [ ] Texture packer.\n\n### Documentation\n\nCheckout the docs [here](https://jerboaburrow.github.io/Hop/), and also the jGL docs [here](https://jerboaburrow.github.io/jGL/)\n\n### Setup\n\n- clone, and init the submodules (you can use ```submodules.sh```)\n- the ```build.sh``` can be used to build\n\n### OSS Dependencies and Licenses\n\n- Freetype is licensed under the The FreeType Project LICENSE\n- GLEW is licensed under aModified BSD License, the Mesa 3-D License (MIT) and the Khronos License (MIT).\n- GLFW is licensed under the zlib/libpng\n- GLM is licensed under the MIT License (but also, no bunnies have been made unhappy)\n- Lua is licensed under the MIT license\n- Miniaudio is licensed under the MIT-0 license\n- stduuid is licensed under the MIT license\n- vorbis and ogg is licensed under a BSD license\n- zlib is licensed under the zlib license\n\nThanks to all the OSS developers: David Turner, Robert Wilhelm, and Werner Lemberg (Freetype), Milan Ikits \u003cmilan ikits[]ieee org\u003e, Marcelo E.
