Generates a shader string that defines the precision of float types in
GLSL shaders. This is particularly needed for fragment shaders in a
GLSL ES context where there is no default precision specified.
Practically, this will return the string 'precision mediump float'
or 'precision highp float' depending on if high precision floats are
determined to be supported.
