PdfTransparencyGroupDevice class abstract interface

Optional richer transparency-group entry used by painting/recording devices that can model isolated and non-isolated group backdrops.

Basic devices continue to receive PdfDevice.beginGroup. bounds and a uniform backdropColor let a canvas backend seed a non-isolated offscreen layer with the group's initial backdrop; isolated explicitly requests a transparent initial backdrop (§11.4.6).
