+/**
+ A XMLHandle is a class that wraps a node pointer with null checks; this is
+ an incredibly useful thing. Note that XMLHandle is not part of the TinyXML
+ DOM structure. It is a separate utility class.
+
+ Take an example:
+ @verbatim
+ <Document>
+ <Element attributeA = "valueA">
+ <Child attributeB = "value1" />
+ <Child attributeB = "value2" />
+ </Element>
+ </Document>
+ @endverbatim
+
+ Assuming you want the value of "attributeB" in the 2nd "Child" element, it's very
+ easy to write a *lot* of code that looks like:
+
+ @verbatim
+ XMLElement* root = document.FirstChildElement( "Document" );
+ if ( root )
+ {
+ XMLElement* element = root->FirstChildElement( "Element" );
+ if ( element )
+ {
+ XMLElement* child = element->FirstChildElement( "Child" );
+ if ( child )
+ {
+ XMLElement* child2 = child->NextSiblingElement( "Child" );
+ if ( child2 )
+ {
+ // Finally do something useful.
+ @endverbatim
+
+ And that doesn't even cover "else" cases. XMLHandle addresses the verbosity
+ of such code. A XMLHandle checks for null pointers so it is perfectly safe
+ and correct to use:
+
+ @verbatim
+ XMLHandle docHandle( &document );
+ XMLElement* child2 = docHandle.FirstChild( "Document" ).FirstChild( "Element" ).FirstChild().NextSibling().ToElement();
+ if ( child2 )
+ {
+ // do something useful
+ @endverbatim
+
+ Which is MUCH more concise and useful.
+
+ It is also safe to copy handles - internally they are nothing more than node pointers.
+ @verbatim
+ XMLHandle handleCopy = handle;
+ @endverbatim
+
+ See also XMLConstHandle, which is the same as XMLHandle, but operates on const objects.

+// ***** AtomicOps
+
+// Atomic operations are provided by the AtomicOps templates class,
+// implemented through system-specific AtomicOpsRaw specializations.
+// It provides several fundamental operations such as Exchange, ExchangeAdd
+// CompareAndSet, and Store_Release. Each function includes several memory
+// synchronization versions, important for multiprocessing CPUs with weak
+// memory consistency. The following memory fencing strategies are supported:
+//
+// - NoSync. No memory synchronization is done for atomic op.
+// - Release. All other memory writes are completed before atomic op
+// writes its results.
+// - Acquire. Further memory reads are forced to wait until atomic op
+// executes, guaranteeing that the right values will be seen.
+// - Sync. A combination of Release and Acquire.
+
+
+// *** AtomicOpsRaw
+
+// AtomicOpsRaw is a specialized template that provides atomic operations
+// used by AtomicOps. This class has two fundamental qualities: (1) it
+// defines a type T of correct size, and (2) provides operations that work
+// atomically, such as Exchange_Sync and CompareAndSet_Release.
+
+// AtomicOpsRawBase class contains shared constants/classes for AtomicOpsRaw.
+// The primary thing is does is define sync class objects, whose destructor and
+// constructor provide places to insert appropriate synchronization calls, on
+// systems where such calls are necessary. So far, the breakdown is as follows:
+//
+// - X86 systems don't need custom syncs, since their exchange/atomic
+// instructions are implicitly synchronized.
+// - PowerPC requires lwsync/isync instructions that can use this mechanism.
+// - If some other systems require a mechanism where syncing type is associated
+// with a particular instruction, the default implementation (which implements
+// all Sync, Acquire, and Release modes in terms of NoSync and fence) may not
+// work. Ii that case it will need to be #ifdef-ed conditionally.

+
+// HastSet and Hash.
+//
+// Hash table, linear probing, internal chaining. One interesting/nice thing
+// about this implementation is that the table itself is a flat chunk of memory
+// containing no pointers, only relative indices. If the key and value types
+// of the Hash contain no pointers, then the Hash can be serialized using raw IO.
+//
+// Never shrinks, unless you explicitly Clear() it. Expands on
+// demand, though. For best results, if you know roughly how big your
+// table will be, default it to that size when you create it.
+//
+// Key usability feature:
+//
+// 1. Allows node hash values to either be cached or not.
+//
+// 2. Allows for alternative keys with methods such as GetAlt(). Handy
+// if you need to search nodes by their components; no need to create
+// temporary nodes.
+//
+

+//

+// ***** LatencyTest
+//
+// LatencyTest utility class wraps the low level LatencyTestDevice and manages the scheduling
+// of a latency test. A single test is composed of a series of individual latency measurements
+// which are used to derive min, max, and an average latency value.
+//
+// Developers are required to call the following methods:
+// SetDevice - Sets the LatencyTestDevice to be used for the tests.
+// ProcessInputs - This should be called at the same place in the code where the game engine
+// reads the headset orientation from LibOVR (typically done by calling
+// 'GetOrientation' on the SensorFusion object). Calling this at the right time
+// enables us to measure the same latency that occurs for headset orientation
+// changes.
+// DisplayScreenColor - The latency tester works by sensing the color of the pixels directly
+// beneath it. The color of these pixels can be set by drawing a small
+// quad at the end of the rendering stage. The quad should be small
+// such that it doesn't significantly impact the rendering of the scene,
+// but large enough to be 'seen' by the sensor. See the SDK
+// documentation for more information.
+// GetResultsString - Call this to get a string containing the most recent results.
+// If the string has already been gotten then NULL will be returned.
+// The string pointer will remain valid until the next time this
+// method is called.

+//

+//
+// 'W', 'S', 'A', 'D' - Move forward, back; strafe left/right.
+// F1 - No stereo, no distortion.
+// F2 - Stereo, no distortion.
+// F3 - Stereo and distortion.

+// Y - Up
+// Z - Back
+// X - Right

+// This needs to be done before obtaining sensor data.
+//
