Up through 1.4, there's no easy way to gray out the text of a component
(say, a button) that uses HTML formatting and is disabled. HTML formatting
would be easier to use if there were such a mechanism. The engineer says:
We'd probably add a property to allow users to turn it on or off
(or to customize the disabled appearance themselves).
Many views do not check whether their containers are disabled. And GlyphView does a check only if its host is a JTextComponent.
We could add checks and paint with "textInactiveText" color if the host is disabled.
