+		 *     Use LLProcess::getPipeName() to generate a unique name
+		 *     guaranteed not to already exist in the registry. <i>Not yet
+		 *     implemented.</i>
+		 *
+		 *   The difference between "pipe", "tpipe" and "npipe" is as follows.
+		 *
+		 *   - "pipe": direct LLProcess to monitor the parent end of the pipe,
+		 *     pumping nonblocking I/O every frame. The expectation (at least
+		 *     for stdout or stderr) is that the caller will listen for
+		 *     incoming data and consume it as it arrives. It's important not
+		 *     to neglect such a pipe, because it's buffered in memory. If you
+		 *     suspect the child may produce a great volume of output between
+		 *     frames, consider directing the child to write to a filesystem
+		 *     file instead, then read the file later.
+		 *
+		 *   - "tpipe": do not engage LLProcess machinery to monitor the
+		 *     parent end of the pipe. A "tpipe" is used only to connect
+		 *     different child processes. As such, it makes little sense to
+		 *     pass an empty @a name. <i>Not yet implemented.</i>
+		 *
+		 *   - "npipe": like "tpipe", but use an OS named pipe with a
+		 *     generated name. Note that @a name is the @em internal name of
+		 *     the pipe in our global registry -- it doesn't necessarily have
+		 *     anything to do with the pipe's name in the OS filesystem. Use
+		 *     LLProcess::getPipeName() to obtain the named pipe's OS
+		 *     filesystem name, e.g. to pass it as the @a name to another
+		 *     LLProcess instance using @a type "file". This supports usage
+		 *     like bash's &lt;(subcommand...) or &gt;(subcommand...)
+		 *     constructs. <i>Not yet implemented.</i>
+		 *
+		 * In all cases the open mode (read, write) is determined by the child
+		 * slot you're filling. Child stdin means select the "read" end of a
+		 * pipe, or open a filesystem file for reading; child stdout or stderr
+		 * means select the "write" end of a pipe, or open a filesystem file
+		 * for writing.
+		 *
+		 * Confusion such as passing the same pipe as the stdin of two
+		 * processes (rather than stdout for one and stdin for the other) is
+		 * explicitly permitted: it's up to the caller to construct meaningful
+		 * LLProcess pipe graphs.

 	An array is a sequence of zero or more LLSD values.
 	
+	Thread Safety
+
+	In general, these LLSD classes offer *less* safety than STL container
+	classes.  Implementations prior to this one were unsafe even when
+	completely unrelated LLSD trees were in two threads due to reference
+	sharing of special 'undefined' values that participated in the reference
+	counting mechanism.
+
+	The dereference-before-refcount and aggressive tree sharing also make
+	it impractical to share an LLSD across threads.  A strategy of passing
+	ownership or a copy to another thread is still difficult due to a lack
+	of a cloning interface but it can be done with some care.
+
+	One way of transferring ownership is as follows:
+
+		void method(const LLSD input) {
+		...
+		LLSD * xfer_tree = new LLSD();
+		{
+			// Top-level values
+			(* xfer_tree)['label'] = "Some text";
+			(* xfer_tree)['mode'] = APP_MODE_CONSTANT;
+
+			// There will be a second-level
+			LLSD subtree(LLSD::emptyMap());
+			(* xfer_tree)['subtree'] = subtree;
+
+			// Do *not* copy from LLSD objects via LLSD
+			// intermediaries.  Only use plain-old-data
+			// types as intermediaries to prevent reference
+			// sharing.
+			subtree['value1'] = input['value1'].asInteger();
+			subtree['value2'] = input['value2'].asString();
+
+			// Close scope and drop 'subtree's reference.
+			// Only xfer_tree has a reference to the second
+			// level data.
+		}
+		...
+		// Transfer the LLSD pointer to another thread.  Ownership
+		// transfers, this thread no longer has a reference to any
+		// part of the xfer_tree and there's nothing to free or
+		// release here.  Receiving thread does need to delete the
+		// pointer when it is done with the LLSD.  Transfer
+		// mechanism must perform correct data ordering operations
+		// as dictated by architecture.
+		other_thread.sendMessageAndPointer("Take This", xfer_tree);
+		xfer_tree = NULL;
+
+
+	Avoid this pattern which provides half of a race condition:
+	
+		void method(const LLSD input) {
+		...
+		LLSD xfer_tree(LLSD::emptyMap());
+		xfer_tree['label'] = "Some text";
+		xfer_tree['mode'] = APP_MODE_CONSTANT;

+/**
+ * This class is a growable buffer between a producer and consumer. It serves
+ * as a queue usable with Boost.Iostreams -- hence, a "stream queue."
+ *
+ * This is especially useful for buffering nonblocking I/O. For instance, we
+ * want application logic to be able to serialize LLSD to a std::ostream. We
+ * may write more data than the destination pipe can handle all at once, but
+ * it's imperative NOT to block the application-level serialization call. So
+ * we buffer it instead. Successive frames can try nonblocking writes to the
+ * destination pipe until all buffered data has been sent.
+ *
+ * Similarly, we want application logic be able to deserialize LLSD from a
+ * std::istream. Again, we must not block that deserialize call waiting for
+ * more data to arrive from the input pipe! Instead we build up a buffer over
+ * a number of frames, using successive nonblocking reads, until we have
+ * "enough" data to be able to present it through a std::istream.
+ *
+ * @note The use cases for this class overlap somewhat with those for the
+ * LLIOPipe/LLPumpIO hierarchies, and indeed we considered using those. This
+ * class has two virtues over the older machinery:
+ *
+ * # It's vastly simpler -- way fewer concepts. It's not clear to me whether
+ *   there were ever LLIOPipe/etc. use cases that demanded all the fanciness
+ *   rolled in, or whether they were simply overdesigned. In any case, no
+ *   remaining Lindens will admit to familiarity with those classes -- and
+ *   they're sufficiently obtuse that it would take considerable learning
+ *   curve to figure out how to use them properly. The bottom line is that
+ *   current management is not keen on any more engineers climbing that curve.
+ * # This class is designed around available components such as std::string,
+ *   std::list, Boost.Iostreams. There's less proprietary code.

+ *   from insert() and find(). This bypasses transform_iterator overhead.
+ * * Since we literally use compile-time types as keys, the essential insert()
+ *   and find() methods accept the key type as a @em template parameter,
+ *   accepting and returning value_type as a normal runtime value. This is to

-// *NOTE: We do not support SSE acceleration on Windows builds.
-// Our minimum specification for the viewer includes 1 GHz Athlon processors,
-// which covers the Athlon Thunderbird series that does not support SSE.
-//
-// Our header files include statements like this
-//   const F32 HAVOK_TIMESTEP = 1.f / 45.f;
-// This creates "globals" that are included in each .obj file.  If a single
-// .cpp file has SSE code generation turned on (eg, llviewerjointmesh_sse.cpp)
-// these globals will be initialized using SSE instructions.  This causes SL
-// to crash before main() on processors without SSE.  Untangling all these 
-// headers/variables is too much work for the small performance gains of 
-// vectorization.
-//
-// Therefore we only support vectorization on builds where the everything is 
-// built with SSE or Altivec.  See https://jira.secondlife.com/browse/VWR-1610
-// and https://jira.lindenlab.com/browse/SL-47720 for details.

+/**
+ * @brief Manage SOCKS 5 UDP proxy and HTTP proxy.
+ *
+ * This class is responsible for managing two interconnected tasks,
+ * connecting to a SOCKS 5 proxy for use by LLPacketRing to send UDP
+ * packets and managing proxy settings for HTTP requests.
+ *
+ * <h1>Threading:</h1>
+ * Because HTTP requests can be generated in threads outside the
+ * main thread, it is necessary for some of the information stored
+ * by this class to be available to other threads. The members that
+ * need to be read across threads are in a labeled section below.
+ * To protect those members, a mutex, mProxyMutex should be locked
+ * before reading or writing those members.  Methods that can lock
+ * mProxyMutex are in a labeled section below. Those methods should
+ * not be called while the mutex is already locked.
+ *
+ * There is also a LLAtomic type flag (mHTTPProxyEnabled) that is used
+ * to track whether the HTTP proxy is currently enabled. This allows
+ * for faster unlocked checks to see if the proxy is enabled.  This
+ * allows us to cut down on the performance hit when the proxy is
+ * disabled compared to before this class was introduced.
+ *
+ * <h1>UDP Proxying:</h1>
+ * UDP datagrams are proxied via a SOCKS 5 proxy with the UDP associate
+ * command.  To initiate the proxy, a TCP socket connection is opened
+ * to the SOCKS 5 host, and after a handshake exchange, the server
+ * returns a port and address to send the UDP traffic that is to be
+ * proxied to. The LLProxy class tracks this address and port after the
+ * exchange and provides it to LLPacketRing when required to. All UDP
+ * proxy management occurs in the main thread.
+ *
+ * <h1>HTTP Proxying:</h1>
+ * This class allows all viewer HTTP packets to be sent through a proxy.
+ * The user can select whether to send HTTP packets through a standard
+ * "web" HTTP proxy, through a SOCKS 5 proxy, or to not proxy HTTP
+ * communication. This class does not manage the integrated web browser
+ * proxy, which is handled in llviewermedia.cpp.
+ *
+ * The implementation of HTTP proxying is handled by libcurl. LLProxy
+ * is responsible for managing the HTTP proxy options and provides a
+ * thread-safe method to apply those options to a curl request
+ * (LLProxy::applyProxySettings()). This method is overloaded
+ * to accommodate the various abstraction libcurl layers that exist
+ * throughout the viewer (LLCurlEasyRequest, LLCurl::Easy, and CURL).
+ *
+ * If you are working with LLCurl or LLCurlEasyRequest objects,
+ * the configured proxy settings will be applied in the constructors
+ * of those request handles.  If you are working with CURL objects
+ * directly, you will need to pass the handle of the request to
+ * applyProxySettings() before issuing the request.
+ *
+ * To ensure thread safety, all LLProxy members that relate to the HTTP
+ * proxy require the LLProxyMutex to be locked before accessing.

+(1.)
+In the shader source, setup defines for the desired configuration.
+When providing multiple shaders (for different presets),
+simply setup the defines differently in multiple files.
+Example,
+
+  #define FXAA_PC 1
+  #define FXAA_HLSL_5 1
+  #define FXAA_QUALITY__PRESET 12
+
+Or,
+
+  #define FXAA_360 1
+  
+Or,
+
+  #define FXAA_PS3 1
+  
+Etc.
+
+(2.)
+Then include this file,
+
+  #include "Fxaa3_11.h"
+
+(3.)
+Then call the FXAA pixel shader from within your desired shader.

+                    INTEGRATION - RGBL AND COLORSPACE
+------------------------------------------------------------------------------
+FXAA3 requires RGBL as input unless the following is set, 
+
+  #define FXAA_GREEN_AS_LUMA 1
+
+In which case the engine uses green in place of luma,
+and requires RGB input is in a non-linear colorspace.
+
+RGB should be LDR (low dynamic range).
+Specifically do FXAA after tonemapping.
+
+RGB data as returned by a texture fetch can be non-linear,
+or linear when FXAA_GREEN_AS_LUMA is not set.
+Note an "sRGB format" texture counts as linear,
+because the result of a texture fetch is linear data.
+Regular "RGBA8" textures in the sRGB colorspace are non-linear.
+
+If FXAA_GREEN_AS_LUMA is not set,
+luma must be stored in the alpha channel prior to running FXAA.
+This luma should be in a perceptual space (could be gamma 2.0).
+Example pass before FXAA where output is gamma 2.0 encoded,
+
+  color.rgb = ToneMap(color.rgb); // linear color output
+  color.rgb = sqrt(color.rgb);    // gamma 2.0 color output
+  return color;
+
+To use FXAA,
+
+  color.rgb = ToneMap(color.rgb);  // linear color output
+  color.rgb = sqrt(color.rgb);     // gamma 2.0 color output
+  color.a = dot(color.rgb, FxaaFloat3(0.299, 0.587, 0.114)); // compute luma
+  return color;
+
+Another example where output is linear encoded,
+say for instance writing to an sRGB formated render target,
+where the render target does the conversion back to sRGB after blending,
+
+  color.rgb = ToneMap(color.rgb); // linear color output
+  return color;
+
+To use FXAA,
+
+  color.rgb = ToneMap(color.rgb); // linear color output
+  color.a = sqrt(dot(color.rgb, FxaaFloat3(0.299, 0.587, 0.114))); // compute luma
+  return color;
+
+Getting luma correct is required for the algorithm to work correctly.
+
+
+------------------------------------------------------------------------------
+                          BEING LINEARLY CORRECT?
+------------------------------------------------------------------------------
+Applying FXAA to a framebuffer with linear RGB color will look worse.
+This is very counter intuitive, but happends to be true in this case.
+The reason is because dithering artifacts will be more visiable 
+in a linear colorspace.
+
+
+------------------------------------------------------------------------------
+                             COMPLEX INTEGRATION
+------------------------------------------------------------------------------
+Q. What if the engine is blending into RGB before wanting to run FXAA?
+
+A. In the last opaque pass prior to FXAA,
+   have the pass write out luma into alpha.
+   Then blend into RGB only.
+   FXAA should be able to run ok
+   assuming the blending pass did not any add aliasing.
+   This should be the common case for particles and common blending passes.
+
+A. Or use FXAA_GREEN_AS_LUMA.

+This optimized version thanks to suggestions from Andy Luedke.

+As of the FXAA 3.11 release, I have still not tested this code,

+And note this is replacing the old unoptimized version.

+       FXAA3 CONSOLE - OPTIMIZED PS3 PIXEL SHADER (WITH EARLY EXIT)
+
+==============================================================================
+The code mostly matches the assembly.
+I have a feeling that 14 cycles is possible, but was not able to get there.
+Might have to increase register count to get full performance.
+Note this shader does not use perspective interpolation.
+
+Use the following cgc options,
+
+ --fenable-bx2 --fastmath --fastprecision --nofloatbindings
+
+Use of FXAA_GREEN_AS_LUMA currently adds a cycle (16 clks).
+Will look at fixing this for FXAA 3.12.

+ * @endcode
+ * or

+ * ensure_contains("exception doesn't mention blah", string, "blah");
+ * @endcode

+ *
+ * The trouble is that when linking to a dynamic libllcommon.so on Linux, we
+ * generally fail to catch the specific exception. Oddly, we can catch it as
+ * std::runtime_error and validate its typeid().name(), so we do -- but that's
+ * a lot of boilerplate per test. Encapsulate with this macro. Usage:
+ *
+ * @code
+ * std::string threw;
+ * try
+ * {
+ *     some_call_that_should_throw_Foo();
+ * }
+ * CATCH_AND_STORE_WHAT_IN(threw, Foo)
