(Whiteboard: webgl-driver)

`int`s coming out of a `ivec4` seem to max out at a value of 2. GLSL precision for `int` should default to mediump, and indeed adding `precision mediump int` doesn't change anything. Add `precision highp int` and it works, though. It would be spec-compliant to supply highp when mediump (or lowp!) is required, so we *could* just do that. FWIW, even lowp ints should have a range of (2^-8, 2^8). Only lowp floats can have a range as small as (-2, 2). Why the driver would supply lowp float functionality for mediump ints is anyone's guess. We should see about injecting `precision highp int` on affected devices. (where available)
