- * Program variable data storage is kept completely transparent to the
- * front-end compiler. It is up to the back-end how the data is
- * actually allocated. The slang_storage_type enum provides the basic
- * information about how the memory is interpreted. This abstract
- * piece of memory is called a data slot. A data slot of a particular
- * type has a fixed size.
- *
- * For now, only the three basic types are supported, that is bool,
- * int and float. Other built-in types like vector or matrix can
- * easily be decomposed into a series of basic types.
- *
- * If the vec4 module is enabled, 4-component vectors of floats are
- * used when possible. 4x4 matrices are constructed of 4 vec4 slots.

- * required to have a size equal to the sum of sizes of its

- * addressing. That is, if B references first data slot in the array,
- * S is the size of the data slot and I is the integral index that is
- * not known at compile time, B+I*S references I-th data slot.
- *
- * This structure is also used to break down built-in data types that
- * are not supported directly. Vectors, like vec3, are constructed
- * from arrays of their basic types. Matrices are formed of an array
- * of column vectors, which are in turn processed as other vectors.
