NOTES:

s indicates a one-, two-, or three-component texture coordinate.
z indicates a depth comparison value for shadow map lookups.
q indicates a perspective value, and is used to divide the texture coordinate ( s ) before the texture lookup is performed.
When you use the texture functions that allow specifying a depth comparison value, the associated texture unit must be configured for depth-compare texturing. Otherwise, no depth comparison will actually be performed.
