Performs a texture lookup with a specified level of detail in sampler \fIsamp\fR using coordinates \fIs\fR.
.SH "PROFILE SUPPORT"
.IX Header "PROFILE SUPPORT"
\&\fBtex2Dlod\fR is supported in fragment profiles starting with fp40 and in vertex profiles 
starting with vp40. Variants with \fItexelOff\fR are only supported in gp4 and newer
profiles. Variants with integer samplers are also only suppported in gp4 and newer profiles.
