MAYAFLUX_API std::shared_ptr< Buffers::TextureBuffer > MayaFlux::choose_image	(	int	desired_channels = 4,
		std::optional< Kakshya::Region >	region = std::nullopt
	)

Present a native open-file dialog filtered to image formats and load the chosen file via IOManager::load_image().

Blocks until the user confirms or cancels. Returns nullptr on cancellation, backend error, or if Portal::System is not initialized.

region	Optional source-pixel rectangle with inclusive end coordinates.
