This:
    https://www.khronos.org/opengl/wiki/Data_Type_(GLSL)
does not indicate that OpenGL has unsigned floats.

I found a reference to 10- and 11-bit unsigned floating-point types, but
I get the impression that they're not language-defined types.
    https://www.oreilly.com/library/view/opengl-programming-guide/9780132748445/app07lev1sec3.html
C would not be able to support a type whose size is not a multiple of
CHAR_BIT (bit fields notwithstanding).
