+(Built-in Functions)
+
+    Add a new section 8.10 "Debug Functions":
+
+    Debug functions are available to both fragment and vertex shaders.
+    They are used to track the execution of a shader by logging
+    passed-in arguments to the shader's info log. That values can be
+    retrieved and validated by the application after shader execution
+    is complete.
+
+    void printMESA(const float value);
+    void printMESA(const int value);
+    void printMESA(const bool value);
+    void printMESA(const vec2 value);
+    void printMESA(const vec3 value);
+    void printMESA(const vec4 value);
+    void printMESA(const ivec2 value);
+    void printMESA(const ivec3 value);
+    void printMESA(const ivec4 value);
+    void printMESA(const bvec2 value);
+    void printMESA(const bvec3 value);
+    void printMESA(const bvec4 value);
+    void printMESA(const mat2 value);
+    void printMESA(const mat3 value);
+    void printMESA(const mat4 value);
