Simple WebGL2 HALF_FLOAT texture test to increase x2 GPU bandwidth
(see the page source).
We need half-precision
floating point for JavaScript too. See also
Float16Array discussion.
Note, that with "#precision mediump" You can get x2 f16 Math acceleration
too on modern Intel (SkyLake), mobile and Nvinia GPU
(NVIDIA
Turing Architecture In-Depth).
See also Matrix multiplication in Compute shaders.
