-Da diese Engine einige Muster und Designkonzepte zeigen soll, versucht sie, unnötigen Ballast zu vermeiden.

 ## Educational
 
 Some arguments for its educational side:
 
--   mix and match of various concepts and paradigms to write expressive but concise code
--   heavily inspired by Rust code
--   math code is eager evaluation but `constexpr` to compensate overheads
--   hides old-style `C` APIs behind a renovated facade
--   it leans heavily on the STL and its algorithms

-# Todo
-
-Here some ideas for improving this tiny engine:
-
-## Rendering
-- [ ] replace the OpenGL renderer with a Vulkan backend
-- [ ] add animatable sprites (access to UV mapping and tiling)
-- [ ] add a SDF based renderer (parametric tiles and font rendering)
-
-## Game Support
-- [ ] audio!
-- [ ] some minimal animation system with tweening with different f-curves
-
-
-## System Level
-
-- [ ] add a `Asset` handler to load cache and manage assets
-- [ ] introspection of file system if we load assset
-
-## Design
-
-- [ ] replace some of the 'unkown source' assets
-
-## Build / Dev Support
-- [ ] add a test rig either with Snitch or Catch2
-- [ ] write some reasonable testcases
-- [ ] add CPU and GPU benchmarks to address various issues
