MobileGlues, which stands for "(on) Mobile, GL uses ES", is a GL implementation running on top of host OpenGL ES 3.x (best on 3.2, minimum 3.0), with running Minecraft: Java Edition in mind.

For Shader Developers

MobileGlues automatically:
- Converts desktop GLSL → GLSL ES
- Removes layout(binding) syntax
- Handles version directives
- Always declare precision explicitly:
```
precision highp float;
precision highp int;
```

MobileGlues (since V1.2.6.0) injects these macros into your shaders:

#define MG_MOBILEGLUES                   // Indicates MobileGlues environment
#define MG_MOBILEGLUES_VERSION 1260      // Version number (e.g. 1260 = V1.2.6)

Use these macros for platform-specific logic:

#ifdef MG_MOBILEGLUES
    #if MG_MOBILEGLUES_VERSION >= 1270
        // Logic for MobileGlues (version >= V1.2.7)
    #else
        // Logic for MobileGlues (version < V1.2.7)
    #endif
#else
    // ...
#endif

If encountering issues:
- Enable Ignore shader/program error, and check the logs (located at /sdcard/MG/latest.log).
