  * SkClipStack::Elements that are equivalent to applying the full stack to the rectangle. The clip
  * stack generation id that represents the list of elements is returned in resultGenID. The
  * initial state of the query rectangle before the first clip element is applied is returned via
  * initialState. Optionally, the caller can request a tighter bounds on the clip be returned via
  * tighterBounds. If not NULL, tighterBounds will always be contained by queryBounds after return.
  * If tighterBounds is specified then it is assumed that the caller will implicitly clip against it.
  * If the caller specifies non-NULL for requiresAA then it will indicate whether anti-aliasing is
  * required to process any of the elements in the result.
  *
  * This may become a member function of SkClipStack when its interface is determined to be stable.
+ * Marked SK_API so that SkLua can call this in a shared library build.
