+ * This file can be used for C & C++ code and the syntax used should follow the same rules.
+ * Some preprocessing is done by the GPU backend to make it GLSL compatible.

+ * IMPORTANT:
+ * - Don't add trailing comma at the end of the enum. Our custom pre-processor will noy trim it

+ * - Always use `u` suffix for enum values. GLSL do not support implicit cast.
+ * - Define all values. This is in order to simplify custom pre-processor code.
+ * - Always use uint32_t as underlying type.
+ * - Use float suffix by default for float literals to avoid double promotion in C++.
+ * - Pack one float or int after a vec3/ivec3 to fullfil alligment rules.
+ *
+ * NOTE: Due to alignment restriction and buggy drivers, do not try to use mat3 inside structs.
+ * NOTE: (UBO only) Do not use arrays of float. They are padded to arrays of vec4 and are not worth

+ *
+ * IMPORTANT: Do not forget to align mat4, vec3 and vec4 to 16 bytes, and vec2 to 8 bytes.
