- * GLSL uniform arrays and structs require special handling.
- *
- * The GL_ARB_shader_objects spec says that if you use
- * glGetUniformLocation to get the location of an array, you CANNOT
- * access other elements of the array by adding an offset to the
- * returned location.  For example, you must call
- * glGetUniformLocation("foo[16]") if you want to set the 16th element
- * of the array with glUniform().
- *
- * HOWEVER, some other OpenGL drivers allow accessing array elements
- * by adding an offset to the returned array location.  And some apps
- * seem to depend on that behaviour.
- *
- * Mesa's gl_uniform_list doesn't directly support this since each
- * entry in the list describes one uniform variable, not one uniform
- * element.  We could insert dummy entries in the list for each array
- * element after [0] but that causes complications elsewhere.
- *
- * We solve this problem by encoding two values in the location that's
- * returned by glGetUniformLocation():
- *  a) index into gl_uniform_list::Uniforms[] for the uniform
- *  b) an array/field offset (0 for simple types)
- *
- * These two values are encoded in the high and low halves of a GLint.
- * By putting the uniform number in the high part and the offset in the
- * low part, we can support the unofficial ability to index into arrays
- * by adding offsets to the location value.

+ *
+ * The GL_ARB_shader_objects spec says that if you use
+ * glGetUniformLocation to get the location of an array, you CANNOT

+ * returned location.  For example, you must call
+ * glGetUniformLocation("foo[16]") if you want to set the 16th element
+ * of the array with glUniform().
+ *
+ * HOWEVER, some other OpenGL drivers allow accessing array elements
+ * by adding an offset to the returned array location.  And some apps
+ * seem to depend on that behaviour.
+ *
+ * Mesa's gl_uniform_list doesn't directly support this since each
+ * entry in the list describes one uniform variable, not one uniform
+ * element.  We could insert dummy entries in the list for each array
+ * element after [0] but that causes complications elsewhere.
+ *
+ * We solve this problem by encoding two values in the location that's
+ * returned by glGetUniformLocation():
+ *  a) index into gl_uniform_list::Uniforms[] for the uniform
+ *  b) an array/field offset (0 for simple types)
+ *
+ * These two values are encoded in the high and low halves of a GLint.
+ * By putting the uniform number in the high part and the offset in the
+ * low part, we can support the unofficial ability to index into arrays
+ * by adding offsets to the location value.
