* Convert the given swizzle into a writemask. In some cases this
* is trivial, in other cases, we'll need to also swizzle the right
* hand side to put components in the right places.
+ * See comment above for more info.
+ * XXX this function could be simplified and should probably be renamed.
* \param swizzle the incoming swizzle
* \param writemaskOut returns the writemask
* \param swizzleOut swizzle to apply to the right-hand-side
