Execution tests for the 'mix' builtin function
S is AbstractFloat, f32, f16
T is S or vecN<S>
@const fn mix(e1: T, e2: T, e3: T) -> T
Returns the linear blend of e1 and e2 (e.g. e1*(1-e3)+e2*e3). Component-wise when T is a vector.
T is AbstractFloat, f32, or f16
T2 is vecN<T>
@const fn mix(e1: T2, e2: T2, e3: T) -> T2
Returns the component-wise linear blend of e1 and e2, using scalar blending factor e3 for each component.
Same as mix(e1,e2,T2(e3)).
