Detailed Description

This implements 1D, 2D, and 3D texture lookup functions, clamps texture coordinates, but.

Assume interpolation/mipmapping and clamping afterwards

src indices are assumed to be integers, even if the int allows floating point values.

All of the parameters such as tuple-size, clamp mode, etc. will be known statically at time of code emission, so they are all template parameters.
