Coordinates to perform the lookup. The bias value should be passed as the last component 
of the coordinate vector.

Performs a texture lookup with bias in sampler \fIsamp\fR using coordinates \fIs\fR.
.SH "PROFILE SUPPORT"
.IX Header "PROFILE SUPPORT"
\&\fBtexRECTbias\fR is supported in fragment profiles starting with fp30 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.
