Description
Consider the statement for a `format` of `GL_RED`:
> Each element is a single red component. The GL converts it to floating point and assembles it into an RGBA element by attaching 0 for green and blue, and 1 for alpha. Each component is clamped to the range [0,1].
This is incorrect. Clamping should only happen for normalized integer internal formats. The ES 3.0 documentation is more correct in this regard.

Research direction
The issue names no source files or tests. Start by locating the glTexImage* reference-page text for the GL_RED format and compare its clamping statement with the ES 3.0 documentation. Done means the wording limits clamping to normalized integer internal formats.
