Description Robin Morisset 2019-07-29 16:13:05 PDT 
For compatibility with HLSL (and with the spec now that I've specified HLSL behavior).
In other words, "max(min(upper, x), lower)" must become "min(max(x, lower), upper)".
Comment 1 Robin Morisset 2019-08-01 11:40:14 PDT 
I've changed the spec to follow SPIR-V behavior (undefined value returned in that case), so this is no longer a "bug", but it would still be slightly nicer for portability to follow HLSL.
Comment 2 Myles C. Maxfield 2020-05-05 00:42:30 PDT 
WHLSL is no longer relevant.
