This is change 1 of 9 that fix problems with the specification of the `vec` class. An implementation that follows the existing specification would not accept common code patterns and would not pass the CTS. None of the existing implementations actually follow the existing specification. This change updates the constructors: * Allow the variadic constructor parameters to be types implicitly convertible to `DataT`. * Allow the variadic constructor parameters to be the swizzle types. * Allow implicit conversions from scalar type `T` to 1-element `vec` where `T` is implicitly convertible to `DataT`. These changes correspond to slides 3 - 7 of the presentation that was discussed in the WG meetings
