+/**
+ * \file lower_varyings_to_packed.cpp
+ *
+ * This lowering pass generates GLSL code that manually packs varyings into
+ * vec4 slots, for the benefit of back-ends that don't support packed varyings
+ * natively.
+ *
+ * For example, the following shader:
+ *
+ * out mat3x2 foo; // location=4, location_frac=0
+ * out vec3 bar[2]; // location=5, location_frac=2
+ *
+ * main()
+ * {
+ * ...
+ * }
+ *
+ * Is rewritten to:
+ *
+ * mat3x2 foo;
+ * vec3 bar[2];
+ * out vec4 packed4; // location=4, location_frac=0
+ * out vec4 packed5; // location=5, location_frac=0
+ * out vec4 packed6; // location=6, location_frac=0
+ *
+ * main()
+ * {
+ * ...
+ * packed4.xy = foo[0];
+ * packed4.zw = foo[1];
+ * packed5.xy = foo[2];
+ * packed5.zw = bar[0].xy;
+ * packed6.x = bar[0].z;
+ * packed6.yzw = bar[1];
+ * }
+ *
+ * This lowering pass properly handles "double parking" of a varying vector
+ * across two varying slots. For example, in the code above, two of the
+ * components of bar[0] are stored in packed5, and the remaining component is
+ * stored in packed6.
+ *
+ * Note that in theory, the extra instructions may cause some loss of
+ * performance. However, hopefully in most cases the performance loss will
+ * either be absorbed by a later optimization pass, or it will be offset by
+ * memory bandwidth savings (because fewer varyings are used).
