[PATCH 2/2] [RENDER] Add panoramiX wrappers for gradients and solid fills

If these aren't wrapped, then procs that are wrapped (such as
RenderChangePicture) will fail in Xinerama when they see the resource
type of a picture created through one of these interfaces is PictureType
and not XRT_PICTURE like those allocated via RenderCreatePicture.
