MagickAutoOrientImage (and more...) functions/type not in Default branch

[top4music]

Hi,

on "go get github.com/gographics/gmagick" it downloads correctly the package but a piece of code is missing.
This:

• magick_wand.go

// Sets the image orientation.
func (mw *MagickWand) SetImageOrientation(orientation OrientationType) error {
	ok := C.MagickSetImageOrientation(mw.mw, C.OrientationType(orientation))
	return mw.getLastErrorIfFailed(ok)
}

// Auto orient the image
func (mw *MagickWand) AutoOrientImage(orientation OrientationType) error {
	ok := C.MagickAutoOrientImage(mw.mw, C.OrientationType(orientation))
	return mw.getLastErrorIfFailed(ok)
}

• ... and is missing his relative file for type definition orientation_type.go

Why this? Can I get the "complete" version in one-line-command?

Thanks
