GNUstep drivers for specific graphics systems
This is the back-end component for the GNUstep GUI Library.
GNUstep is a cross-platform, object-oriented set of frameworks for desktop application development. The set of frameworks, based on Cocoa (previously OpenStep), enables developers to rapidly build sophisticated software by employing a large library of reusable software components.
This GUI uses an abstraction layer to talk to the windowing system. It uses the GNUstep back library to handle all of the windowing-system-specific details. It currently works via a DPS emulation engine to emulate the DPS functions required by the front-end system.
More recently, a back end based on Cairo was implemented. This is a high-performance 2D graphics library supporting vector and composing operations.
Another back-end runs on top of the X Window System and uses only Xlib calls for graphics, but seems deprecated. (There is also a back end supporting the Windows GDI, allowing GNUstep applications to run on Windows)
