Krypton Wrapper (NG-GL4ES)

Krypton Wrapper (aka NG-GL4ES) is an OpenGL-to-OpenGL ES translation layer, forked from gl4es and gl4es-114-extra, with modern enhancements targeting Android.

1. Capability to handle more advanced shaders (GLSL → SPIR-V → ESSL via glslang & SPIRV-Cross);
2. Capability to run Minecraft in almost all versions;
3. More advanced OpenGL features on GLES hardware.
