Description Said Abou-Hallawa 2023-09-07 15:09:19 PDT

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.
