		Quartz Compositor is the windowing system that is responsible for the user interface in Mac OS X. On a Mac OS X system, the Quartz Compositor can be seen in a process list as Window Manager or, in more recent versions, WindowServer.
		Quartz 2D is the primary graphics library in Mac OS X. It supersedes QuickDraw, which was used in earlier versions of the Mac OS, now known as Classic.
		Quartz is the graphics layer that sits on top of the Darwin core of Mac OS X, sometimes also referred to as CoreGraphics.

		Quartz 2D running in software using the CPU has to write to the backing store in RAM, then that backing store has to be moved to the video card where the Quartz Compositor can put it into the final scene.
		Quartz 2D Extreme running on the GPU writes those 640,000 pixels into the backing store in VRAM, which is exactly where the Quartz Compositor needs to read it from.
		Quartz 2D was notoriously slow at drawing lines in Panther and earlier versions of Mac OS X, so much so that developers often chose to use (or in most cases, "stick with") QuickDraw for such tasks.

	LinuxDevCenter.com -- What Is Quartz (or Why Can't Windows Do That)
		Quartz is the heart and soul of Mac OS X's graphics layer, which directly supports the defining features of the Aqua desktop experience.
		Quartz Compositor is OS X's powerful window server, and Quartz 2D is the two-dimensional drawing engine that's often referred to as Core Graphics.
		Although Quartz is a catch-all phrase referring to the graphics layer that sits on top of Darwin, it really encompasses two distinct, but closely related, components: a window server called Quartz Compositor and a graphics library called Quartz 2D.

	How Extreme Is 'Quartz Extreme? Very, According To Apple - A Performance Report
		For those of you that haven't heard, Quartz Extreme is Apples name for the way Apple has coded the rendering of the Quartz Graphics layer in OS 10.2 to be done largely by the graphics card.
		Using three utilities he was able to turn Quartz Extreme off and on, and display how that affected processor usage and the compositing frame rate of the Quartz layer.
		Quartz Extreme has been turned on once again, off-loading graphics rendering to the graphics card (probably the NVIDIA GeForce4 Ti, in the demonstration machine), Becuase the graphics card is more efficient at processing graphics data the number of frames per second goes up and bandwidth usage of the processors drops dramatically.

		Quartz Compositor then takes each window bitmap and composites them together using the associated information to create a display.
		This allows the Mac OS X windowing system to be "''agnostic in terms of a drawing model''" and gives it the ability to create impressive visual effects, such as the ''genie effect'' as a window is minimized to the Dock.
		The Quartz Compositor takes the events from the queue, determines which process owns the window where the event occurred and passes the event on to the process's own event queue.

	IGM: OS X Journal: Closer look at Jaguar's Quartz Extreme
		Quartz Extreme will allow Mac OS X to offload most of these Quartz graphics to the graphics card, freeing up a significant portion of the CPU to work on other tasks.
		Quartz Extreme is progress and to require the use of current hardware to take advantage of it isn't unreasonable at all.
		Quartz Extreme hardware-accelleration via OpenGL is a positive and applaudable step to take - it removes a large workload from the CPU and congestion of the RAM bus, and it allows Apple to improve hardware through other means than MHz increases.

		Graphic design is the one industry that apple still have a death grip on, though the numbers are slipping in this area, same as education, another Apple stronghold once upon a time.

	MacGamer - Get In The Game
		Quartz, for those of you who have been asleep all this time, is the underlying graphics layer for Mac OS X It handles everything from such glorious tasks as drawing text on the screen to your mundane, everyday genie effects.
		In fact, Quartz is so advanced that the normal 2D acceleration features of most graphics cards cannot accelerate Quartz’s features.
		Quite literally, actually; while the details of exactly how Quartz Extreme will work at this point are skimpy due to the blanket NDA Apple’s put over everything, what we do know is that it uses the OpenGL features on newer video cards to speed everything up, probably to previously unheard-of speed.

	biology - GDI
		GDI is short for Graphics Device Interface, and is one of the three core components or "subsystems" of Microsoft Windows.
		GDI+ is a "next generation" 2D graphics environment, adding advanced features such as alpha blending, gradient shading, more complex path management, intrinsic support for modern graphics-file formats like JPEG and PNG (which were conspicuously absent in GDI), and general support for composition of affine transformations in the 2D view pipeline.
		Use of these features are apparent in Windows XP's user interface, and their presence in the basic graphics layer greatly simplifies implementations of vector-graphics systems such as flash or SVG.

	Ancient Creature Fossilized By The Bacteria That Ate It
		Loren Babcock, professor of geological sciences at Ohio State, and his colleagues used a scanning electron microscope to examine fossils of tiny arthropods they collected from Antarctica, and discovered that the arthropod fossils were actually composed of clumps of even tinier bacteria fossils.
		The scientists suspect that the bacteria feasted on the dead arthropods, then absorbed minerals from their surroundings and turned to quartz, preserving perfectly the shape and texture of the arthropods.
		Though the scientists could see arthropod fossils exposed in the rock as they gathered their samples, it wasn't until they returned to Ohio and put the limestone under a scanning electron microscope (SEM) that they saw the fossilized eubacteria.

		This second team performed optically stimulated luminiscence tests (subtly different from thermoluminescence) on the quartz grains and made radiocarbon measurements on charcoal fragments (from human activity) in the same sediment layer.
		Quartz found near the top of the sediment appears to be 2,200 years old while grains found at the maximum burial depth (two meters) measured roughly 22,000 years old.
		In the very layer that produced the 60,000-year thermoluminescence date, the radiometric tests showed the charcoal to be 1,000 to 3,000 years old.

	Mac Web Browsers Draw Battle Lines - -
		The most visually striking advancement made in two of the latest OS X-compliant Web browsers is the utilization of Quartz -- Apple's graphics layer that provides real-time rendering, compositing of PostScript-level graphics, and anti-aliasing.
		Quartz allows for effects like drop shadows around the edges of windows, translucent menus and ColorSync correction.
		Dubbed Chimera, the browser is simple in its current form but offers the most stable build yet of a Netscape-based product on Mac OS X. Integrating a sidebar, Chimera performs some of the functions necessary to general browsing in an exceptional manner but lacks critical features like support for plug-ins.

		Second they can rendered with Quartz, this will maintain most of the original appearance and add some Quartz features such as anti-aliasing (i.e., it will remove the "jaggies"), but the pictures still can't be edited.
		Finally, QuickDraw pictures and ClarisDraw graphics can be converted to Quartz graphics allowing them to be edited, but this may introduce various artifacts due to the differences between QuickDraw and Quartz.
		In some cases, ignoring the transfer mode causes a graphic to change its appearance or even become visible where it was originally invisible.
