-----------
Associate a purpose for each GraphicsContextState in the context state stack
https://bugs.webkit.org/show_bug.cgi?id=261296
rdar://115138846
Reviewed by Simon Fraser.
We internally call GraphicsContext::save() when we begin a transparency layer
and
we call GraphicsContext::restore() when we end the transparency layer.
Differentiating when this happens from normal save/restore will make it easy to
unwind the stack of the GraphicsContextState and the transparency layers in the
right order.
