LocaleStringAttribute
A string attribute that causes the assistive technologies, e.g. VoiceOver,
to treat string as a certain language.
MaskFilter
A mask filter to apply to shapes as they are painted. A mask filter is a
function that takes a bitmap of color pixels, and returns another bitmap of
color pixels.
