		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.

		Quartz is a VERY common mineral, and is often found as veins cutting through all kinds of rock in most parts of the world.
		Quartz is very abundant in the Earth’s crust so there is no danger of running short of easily available raw quartz for cultured quartz production.
		Quartz crystal is the most abundant crystalline form of silicon dioxide, occurring, in some parts of the world, in large single crystals from which mechanical resonators of useful dimensions can readily be formed.

	MacDevCenter.com -- Introduction to Quartz 2D for QuickDraw Programmers (Site not responding. Last check: 2007-10-11)
		Quartz 2D is a key component of the Core Graphics architecture of Mac OS X, and is the modern technology in the system whose functionality most closely matches that of QuickDraw.
		For this reason, the unit defined for the coordinate axes in Quartz 2D is the point that is defined to be exactly 1/72 of an inch (or to put it another way, there are 72 points per inch).
		It is possible to change the Quartz context's coordinate system so that one inch of user space no longer equals one inch on the output device, but when the context is first created, the convention is that Quartz sets it up so that 72 points in user space equals one inches worth of device pixels.

	MacDevCenter.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.

	Quartz 2D - Wikipedia, the free encyclopedia
		Quartz 2D is the primary graphics library in Mac OS X.
		Quartz 2D is based on version 1.4 of the Adobe Portable Document Format (PDF – a universal file format that preserves all of the fonts, formatting, colors and graphics of any source document, regardless of the platform used to create it).
		Quartz 2D instead takes a more mathematical approach, where the coordinate space is an abstract concept defined by real values in 2 dimensions.

		At the time Quartz 2D receives the close instruction, if the first and last points of the path do not match, the computer will add a final segment from the last point to the first point.
		With Quartz 2D you are more likely to see a white screen than a fl one, but the underlying cause is the same.
		Rotation angles in Quartz 2D, however, are specified in radians, not degrees.

	Quartz (graphics layer) - Wikipedia, the free encyclopedia
		There are two components that make up Quartz: Quartz Compositor, a compositing windowing system that manages and composites off-screen window bitmaps to create the Mac OS X user interface; and Quartz 2D, a two dimensional text and graphics drawing library based on the paradigms of the Portable Document Format.
		Quartz can render text with sub-pixel precision; graphics are limited to more traditional anti-aliasing, which is the default mode of operation but can be turned off.
		Quartz 2D Extreme was introduced in Mac OS X Tiger, but was disabled by default; Apple strongly cautioned against using it because of bugs which could cause visual anomalies and crashes.

		Quartz is the umbrella term for the Mac OS X display layer through which all drawing and screen display is done.
		Quartz takes advantage of this to enable nearly anything drawn to the screen to be written to a PDF file, and to help unify printing and screen display under a single API.
		That leaves Quartz 2D and QuickDraw, the two general purpose drawing APIs in Mac OS X. Quartz 2D is Mac OS X's "native" drawing API.

		Apple has choosen not to enable Quartz 2D Extreme for a good reason and that is because it currently does not provide any significant performance advantage and in some cases actually might be slower.
		Quartz 2D Extreme is something meant only for 2D not 3D.
		I just realized this and am really sorry for this, but Quartz 2D Extreme is not supported on the 855, even after editing of both the plists in Method 1 and 2.

	From QuickDraw to Quartz 2D > The Legacy of QuickDraw and the Rise of PDF (Site not responding. Last check: 2007-10-11)
		Moreover, Quartz 2D is a single part in a larger graphics architecture on Mac OS X. This architecture was designed from its inception to take advantage of advances in the graphics hardware of modern personal computers.
		The Quartz 2D library has a long legacy behind it and understanding that legacy may help you to recognize some of the idiosyncrasies of the library’s imaging model.
		Instead of erasing graphics, in Quartz 2D you create a mask, or clipping area, and draw the graphics you want the user to see relying on the mask to remove parts of the image you don’t want to display.

	MacDevCenter.com -- What Is Quartz (or Why Can't Windows Do That)
		Because Quartz is rooted in the PDF specification, it shouldn't come as any surprise to you that Quartz 2D provides a rich API for drawing to OpenGL graphics contexts, PDF and PostScript documents, and raster graphics (bitmaps), in addition to the screen.
		Quartz is highly customizable and includes the ability to specify whether or not to anti-alias graphics and text, manage color with ColorSync, internally compress data, and specify the level of transparency among other things.
		If all of that talk about Quartz 2D sounds pretty intense, you'll be glad to know that there's still a lot of fun that you can have without writing a single line of code.

		The new quartz products are nonporous so they don’t stain and their colors and patterns are consistent so you don’t have to worry about picking out a particular slab—the color you pick out in the showroom will be the one you get.
		They say this is because it has "become a cult record", but this lione veils a rather unusual situation as Quartz were dropped by Jet after the one LP and have recently re-emerged on the small independent Reddington's, based on the well known Rare Records shop in Birmingham.
		They have had an Alternative Chart hit with their new single 'Nantucket Sleighride' and a new album is due out any day, so this seems to be a case of a major label rising on the back of an independent's sucess.

	cybergrain: Apple Quartz, Windows Vista, and the 3D pipeline
		Apple's OS X 10.2 (Jaguar) in 2002 was the first operating system to start moving some of their 2D graphics onto the 3D pipeline with a technology called Quartz Extreme.
		This year, OS X Tiger included Quartz Extreme 2D (see here), which moved all 2D operations over to the 3D pipe.
		For every 2D drawing routine like PaintPoly in Quartz, a new version was required which does its work by first "tesselating" the shape into triangles and then passing the triangles to the 3D pipeline.

		Quartz, also known as Core Graphics, is the native graphics API for OS X. Now, that QuickDraw has been deprecated, it has become more important to learn and master Quartz.
		Quartz uses floats in point and rectangle structures so it can represent more accurate values during scaling, rotation, and other transforms.
		By default, Quartz uses a coordinate system with 0.0, 0.0 as the lower, left corner, as opposed to QuickDraw with 0,0 on the top, left.

	Inside Mac Games Feature: A Look At Mac OS X 10.2
		Quartz Extreme makes your entire 2D workspace an OpenGL scene, in which each window is a textured polygon.
		It also accelerates the Quartz effects, such as "genie" and "scale" which are used when minimizing windows to the Dock.
		But the real benefit of Quartz Extreme is not its butter-smooth eye candy; with all of the graphics work being done by the GPU on your graphics card, your CPU is freed up to work on other things.

	IGM: OS X Journal: Closer look at Jaguar's Quartz Extreme
		Quartz Extreme is progress and to require the use of current hardware to take advantage of it isn't unreasonable at all.
		Most current 2D accelerators sort of take this for granted, and their drivers and hardware are built assuming that one process owns the drawing canvas.
		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.

	RoughlyDrafted: Remote Display part 6
		The Quartz Compositor is particularly amazing because it layers windows with active transparency, providing subtle effects like drop shadows and translucent windows.
		Drawing in Mac OS X is done outside of the Quartz Compositor, either in legacy QuickDraw, in the new Quartz 2D (which follows the graphics model of PDF), in OpenGL (for 3D models), or in QuickTime (for 4D video).
		While this is certainly an interesting option, Apple development in the last five years has centered on improving Quartz Compositor and Quartz 2D for local performance, accelerating both using the otherwise idle graphic CPU.
