Source/WebCore:

Added the -webkit-mask-source-type property, which can have a value of auto, alpha or
luminance. The default value is auto. This patch contains only the parsing of the property,
not the actual implementation of the types of masks. The parsing of mask-source-type in the
-webkit-mask property will be handled in a separate patch.
