- * Given a semantic name and index of a parameter and a mask of used parameters
- * (inputs or outputs), return the index of the parameter in the list of all
- * used parameters.
- *
- * For example, assume this list of parameters:
- *   POSITION, PSIZE, GENERIC0, GENERIC2
- * which has the mask:
- *   11000000000101
- * Then:
- *   querying POSITION returns 0,
- *   querying PSIZE returns 1,
- *   querying GENERIC0 returns 2,
- *   querying GENERIC2 returns 3.
- *
- * Which can be used as an offset to a parameter buffer in units of vec4s.
