+ * This pass accounts for the difference between the way
+ * gl_ClipDistance is declared in standard GLSL (as an array of
+ * floats), and the way it is frequently implemented in hardware (as
+ * a pair of vec4s, with four clip distances packed into each).
+ *
+ * The declaration of gl_ClipDistance is replaced with a declaration
+ * of gl_ClipDistanceMESA, and any references to gl_ClipDistance are
+ * translated to refer to gl_ClipDistanceMESA with the appropriate
+ * swizzling of array indices. For instance:
+ *
+ * gl_ClipDistance[i]
+ *
+ * is translated into:
+ *
+ * gl_ClipDistanceMESA[i>>2][i&3]
+ *
+ * Since some hardware may not internally represent gl_ClipDistance as a pair
+ * of vec4's, this lowering pass is optional. To enable it, set the
+ * LowerClipDistance flag in gl_shader_compiler_options to true.
