Constructor

eZImageTextLayer::mergeLayer	(	$	image,
		$	layerData,
		$	lastLayerData
	)

Renders the text with the other layer data. It will perform something that will look like alphablending of the text.

It will copy the area which it will render on from the other layer and render on it and then merge the result back on the other layer using the transparency value. This means that the original image data is kept and the actual text will be transparent.

Reimplemented from eZImageLayer.
