+// The following helper template addresses a corner case in range checks for
+// conversion from a floating-point type to an integral type of smaller range
+// but larger precision (e.g. float -> unsigned). The problem is as follows:
+//   1. Integral maximum is always one less than a power of two, so it must be
+//      truncated to fit the mantissa of the floating point. The direction of
+//      rounding is implementation defined, but by default it's always IEEE
+//      floats, which round to nearest and thus result in a value of larger
+//      magnitude than the integral value.
+//      Example: float f = UINT_MAX; // f is 4294967296f but UINT_MAX
+//                                   // is 4294967295u.
+//   2. If the floating point value is equal to the promoted integral maximum
+//      value, a range check will erroneously pass.
+//      Example: (4294967296f <= 4294967295u) // This is true due to a precision
+//                                            // loss in rounding up to float.
+//   3. When the floating point value is then converted to an integral, the
+//      resulting value is out of range for the target integral type and
+//      thus is implementation defined.
+//      Example: unsigned u = (float)INT_MAX; // u will typically overflow to 0.
+// To fix this bug we manually truncate the maximum value when the destination
+// type is an integral of larger precision than the source floating-point type,
+// such that the resulting maximum is represented exactly as a floating point.

+
+If you want to understand the MurmurHash algorithm you would be much better
+off reading the original source. Just point your browser at:
+http://code.google.com/p/smhasher/source/browse/trunk/MurmurHash3.cpp
+
+
+What this version provides?
+
+1. Progressive data feeding. Useful when the entire payload to be hashed
+does not fit in memory or when the data is streamed through the application.
+Also useful when hashing a number of strings with a common prefix. A partial
+hash of a prefix string can be generated and reused for each suffix string.
+
+2. Portability. Plain old C so that it should compile on any old compiler.
+Both CPU endian and access-alignment neutral, but avoiding inefficient code
+when possible depending on CPU capabilities.
+
+3. Drop in. I personally like nice self contained public domain code, making it
+easy to pilfer without loads of refactoring to work properly in the existing
+application code & makefile structure and mucking around with licence files.
+Just copy PMurHash.h and PMurHash.c and you're ready to go.
+
+
+How does it work?
+
+We can only process entire 32 bit chunks of input, except for the very end
+that may be shorter. So along with the partial hash we need to give back to
+the caller a carry containing up to 3 bytes that we were unable to process.
+This carry also needs to record the number of bytes the carry holds. I use
+the low 2 bits as a count (0..3) and the carry bytes are shifted into the
+high byte in stream order.
+
+To handle endianess I simply use a macro that reads a uint32_t and define
+that macro to be a direct read on little endian machines, a read and swap
+on big endian machines, or a byte-by-byte read if the endianess is unknown.

+/*!XXH_FORCE_MEMORY_ACCESS :
+ * By default, access to unaligned memory is controlled by `memcpy()`, which is safe and portable.
+ * Unfortunately, on some target/compiler combinations, the generated assembly is sub-optimal.
+ * The below switch allow to select different access method for improved performance.
+ * Method 0 (default) : use `memcpy()`. Safe and portable.
+ * Method 1 : `__packed` statement. It depends on compiler extension (ie, not portable).
+ *            This method is safe if your compiler supports it, and *generally* as fast or faster than `memcpy`.
+ * Method 2 : direct access. This method doesn't depend on compiler but violate C standard.
+ *            It can generate buggy code on targets which do not support unaligned memory accesses.
+ *            But in some circumstances, it's the only known way to get the most performance (ie GCC + ARMv6)
+ * See http://stackoverflow.com/a/32095106/646947 for details.
+ * Prefer these methods in priority order (0 > 1 > 2)

+// Symbol table for parsing.  Has these design characteristics:
+//
+// * Same symbol table can be used to compile many shaders, to preserve
+//   effort of creating and loading with the large numbers of built-in
+//   symbols.
+//
+// * Name mangling will be used to give each function a unique name
+//   so that symbol table lookups are never ambiguous.  This allows
+//   a simpler symbol table structure.
+//
+// * Pushing and popping of scope, so symbol table will really be a stack
+//   of symbol tables.  Searched from the top, with new inserts going into
+//   the top.
+//
+// * Constants:  Compile time constant symbols will keep their values
+//   in the symbol table.  The parser can substitute constants at parse
+//   time, including doing constant folding and constant propagation.
+//
+// * No temporaries:  Temporaries made from operations (+, --, .xy, etc.)
+//   are tracked in the intermediate representation, not the symbol table.

+        // the same.  Furthermore, ma0 and ma1 may not be the same.  This makes it impossible to
+        // derive dUV from dP exactly.
+        //
+        // However, gradient transformation is implementation dependant, so we will simplify and

+//     that comes from a series of assignments, possibly with swizzled or ternary operators with
+//     known conditionals, where the source is before the loop.
+//     So, a workaround is to add a +0 term to variables the first time they are assigned to in
+//     an inner loop (if they are declared in an outside scope, otherwise there is no need).
+//     This will break the aliasing chain.
+
+// For simplicity here we add a +0 to any assignment that is in at least two nested loops. Because

+// Walks the tree to rebuild nodes.
+// This class is intended to be derived with overridden visitXXX functions.
+//
+// Each visitXXX function that does not have a Visit parameter simply has the visitor called
+// exactly once, regardless of (preVisit) or (postVisit) values.
+
+// Each visitXXX function that has a Visit parameter behaves as follows:
+//    * If (preVisit):
+//      - The node is visited before children are traversed.
+//      - The returned value is used to replace the visited node. The returned value may be the same
+//        as the original node.
+//      - If multiple nodes are returned, children and post visits of the returned nodes are not
+//        preformed, even if it is a singleton collection.
+//    * If (childVisit)
+//      - If any new children are returned, the node is automatically rebuilt with the new children
+//        before post visit.
+//      - Depending on the type of the node, null children may be discarded.
+//      - Ill-typed children cause rebuild errors. Ill-typed means the node to automatically rebuild
+//        cannot accept a child of a certain type as input to its constructor.
+//      - Only instances of TIntermAggregateBase can accept Multi results for any of its children.
+//        If supplied, the nodes are spliced children at the spot of the original child.
+//    * If (postVisit)
+//      - The node is visited after any children are traversed.
+//      - Only after such a rebuild (or lack thereof), the post-visit is performed.
+//
+// Nodes in visit functions are allowed to be modified in place, including TIntermAggregateBase
+// child sequences.
+//
+// The default implementations of all the visitXXX functions support full pre and post traversal
+// without modifying the visited nodes.

+//    The assumption is that ES2 validation will not check textureSupport for sized formats.
+//
+// 2. Sized half float types are a combination of GL_HALF_FLOAT and GL_HALF_FLOAT_OES support,
+//    due to a limitation that only one type for sized formats is allowed.

+// Trace events are for tracking application performance and resource usage.
+// Macros are provided to track:
+//    Begin and end of function calls
+//    Counters
+//
+// Events are issued against categories. Whereas LOG's
+// categories are statically defined, TRACE categories are created
+// implicitly with a string. For example:
+//   TRACE_EVENT_INSTANT0("MY_SUBSYSTEM", "SomeImportantEvent")
+//
+// Events can be INSTANT, or can be pairs of BEGIN and END in the same scope:
+//   TRACE_EVENT_BEGIN0("MY_SUBSYSTEM", "SomethingCostly")
+//   doSomethingCostly()
+//   TRACE_EVENT_END0("MY_SUBSYSTEM", "SomethingCostly")
+// Note: our tools can't always determine the correct BEGIN/END pairs unless
+// these are used in the same scope. Use ASYNC_BEGIN/ASYNC_END macros if you need them
+// to be in separate scopes.
+//
+// A common use case is to trace entire function scopes. This
+// issues a trace BEGIN and END automatically:
+//   void doSomethingCostly() {
+//     TRACE_EVENT0("MY_SUBSYSTEM", "doSomethingCostly");
+//     ...
+//   }
+//
+// Additional parameters can be associated with an event:
+//   void doSomethingCostly2(int howMuch) {
+//     TRACE_EVENT1("MY_SUBSYSTEM", "doSomethingCostly",
+//         "howMuch", howMuch);
+//     ...
+//   }
+//
+// The trace system will automatically add to this information the
+// current process id, thread id, and a timestamp in microseconds.
+//
+// To trace an asynchronous procedure such as an IPC send/receive, use ASYNC_BEGIN and
+// ASYNC_END:
+//   [single threaded sender code]
+//     static int send_count = 0;
+//     ++send_count;
+//     TRACE_EVENT_ASYNC_BEGIN0("ipc", "message", send_count);
+//     Send(new MyMessage(send_count));
+//   [receive code]
+//     void OnMyMessage(send_count) {
+//       TRACE_EVENT_ASYNC_END0("ipc", "message", send_count);
+//     }
+// The third parameter is a unique ID to match ASYNC_BEGIN/ASYNC_END pairs.
+// ASYNC_BEGIN and ASYNC_END can occur on any thread of any traced process. Pointers can
+// be used for the ID parameter, and they will be mangled internally so that
+// the same pointer on two different processes will not match. For example:
+//   class MyTracedClass {
+//    public:
+//     MyTracedClass() {
+//       TRACE_EVENT_ASYNC_BEGIN0("category", "MyTracedClass", this);
+//     }
+//     ~MyTracedClass() {
+//       TRACE_EVENT_ASYNC_END0("category", "MyTracedClass", this);
+//     }
+//   }
+//
+// Trace event also supports counters, which is a way to track a quantity
+// as it varies over time. Counters are created with the following macro:
+//   TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter", g_myCounterValue);
+//
+// Counters are process-specific. The macro itself can be issued from any
+// thread, however.
+//
+// Sometimes, you want to track two counters at once. You can do this with two
+// counter macros:
+//   TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter0", g_myCounterValue[0]);
+//   TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter1", g_myCounterValue[1]);
+// Or you can do it with a combined macro:
+//   TRACE_COUNTER2("MY_SUBSYSTEM", "myCounter",
+//       "bytesPinned", g_myCounterValue[0],
+//       "bytesAllocated", g_myCounterValue[1]);
+// This indicates to the tracing UI that these counters should be displayed
+// in a single graph, as a summed area chart.
+//
+// Since counters are in a global namespace, you may want to disembiguate with a
+// unique ID, by using the TRACE_COUNTER_ID* variations.
+//
+// By default, trace collection is compiled in, but turned off at runtime.
+// Collecting trace data is the responsibility of the embedding
+// application. In Chrome's case, navigating to about:tracing will turn on
+// tracing and display data collected across all active processes.
+//
+//
+// Memory scoping note:
+// Tracing copies the pointers, not the string content, of the strings passed
+// in for category, name, and arg_names. Thus, the following code will
+// cause problems:
+//     char* str = strdup("impprtantName");
+//     TRACE_EVENT_INSTANT0("SUBSYSTEM", str);  // BAD!
+//     free(str);                   // Trace system now has dangling pointer
+//
+// To avoid this issue with the |name| and |arg_name| parameters, use the
+// TRACE_EVENT_COPY_XXX overloads of the macros at additional runtime overhead.
+// Notes: The category must always be in a long-lived char* (i.e. static const).
+//        The |arg_values|, when used, are always deep copied with the _COPY
+//        macros.
+//
+// When are string argument values copied:
+// const char* arg_values are only referenced by default:
+//     TRACE_EVENT1("category", "name",
+//                  "arg1", "literal string is only referenced");
+// Use TRACE_STR_COPY to force copying of a const char*:
+//     TRACE_EVENT1("category", "name",
+//                  "arg1", TRACE_STR_COPY("string will be copied"));
+// std::string arg_values are always copied:
+//     TRACE_EVENT1("category", "name",
+//                  "arg1", std::string("string will be copied"));
+//
+//
+// Thread Safety:
+// A thread safe singleton and mutex are used for thread safety. Category
+// enabled flags are used to limit the performance impact when the system
+// is not enabled.
+//
+// TRACE_EVENT macros first cache a pointer to a category. The categories are
+// statically allocated and safe at all times, even after exit. Fetching a
+// category is protected by the TraceLog::lock_. Multiple threads initializing
+// the static variable is safe, as they will be serialized by the lock and
+// multiple calls will return the same pointer to the category.
+//
+// Then the category_enabled flag is checked. This is a unsigned char, and
+// not intended to be multithread safe. It optimizes access to addTraceEvent
+// which is threadsafe internally via TraceLog::lock_. The enabled flag may
+// cause some threads to incorrectly call or skip calling addTraceEvent near
+// the time of the system being enabled or disabled. This is acceptable as
+// we tolerate some data loss while the system is being enabled/disabled and
+// because addTraceEvent is threadsafe internally and checks the enabled state
+// again under lock.
+//
+// Without the use of these static category pointers and enabled flags all
+// trace points would carry a significant performance cost of aquiring a lock
+// and resolving the category.
