Detailed Description

Interface class for graphics context objects, used internally by the Graphics class.

Users are not supposed to create instances of this class directly - do your drawing via the Graphics object instead.

It's a base class for different types of graphics context, that may perform software-based or OS-accelerated rendering.

E.g. the LowLevelGraphicsSoftwareRenderer renders onto an image in memory, but other subclasses could render directly to a windows HDC, a Quartz context, or an OpenGL context.
