- * GLSL allows shader writers to allocate vertex result attributes (varyings) in
- * single float component granularity. This is in contrast to vertex / fragment
- * programs, where result attributes (actually texcoords) were allocated
- * in 4-component vectors of floats granularity.
- * For performance reasons, it would be optimal to stick with this scheme on a scalar
- * processor. Varyings will likely be allocated as 3-component vectors, so statistically
- * we win 2 floats.
- * The constant VARYINGS_PER_VECTOR tells us how much of float components we pack into
- * one result vector. For scalar processor it would be 1, for vector processor - 4.
- *
- * NOTE: Currently we pack varyings into vertex attributes.
