+//  cmap if font is used with a simple font dict and not a CIDFont dict
+//
+// Other tables we need to keep for PDF rendering to support zoom in/out:
+//  bdat, bloc, ebdt, eblc, ebsc, gasp
+//
+// Special table:
+//  CFF - if you have this table then you shouldn't have a glyf table and this
+//        is the table with all the glyphs.  Shall skip subsetting completely
+//        since sfntly is not capable of subsetting it for now.
+//  post - extra info here for printing on PostScript printers but maybe not
+//         enough to outweigh the space taken by the names
+//
+// Tables to break apart:
+//  name - could throw away all but one language and one platform strings/ might
+//         throw away some of the name entries
+//  cmap - could strip out non-needed cmap subtables
+//       - format 4 subtable can be subsetted as well using sfntly
+//
+// Graphite tables:
+//  silf, glat, gloc, feat - should be okay to strip out
+//
+// Tables that can be discarded:
+//  OS/2 - everything here is for layout and description of the font that is
+//         elsewhere (some in the PDF objects)
+//  BASE, GDEF, GSUB, GPOS, JSTF - all used for layout
+//  kern - old style layout
+//  DSIG - this will be invalid after subsetting
+//  hdmx - layout
+//  PCLT - metadata that's not needed
+//  vmtx - layout
+//  vhea - layout
+//  VDMX

+// Object reference count and smart pointer implementation.
+
+// Smart pointer usage in sfntly:
+//
+// sfntly carries a smart pointer implementation like COM.  Ref-countable object
+// type inherits from RefCounted<>, which have AddRef and Release just like
+// IUnknown (but no QueryInterface).  Use a Ptr<> based smart pointer to hold
+// the object so that the object ref count is handled correctly.
+//
+// class Foo : public RefCounted<Foo> {
+//  public:
+//   static Foo* CreateInstance() {
+//     Ptr<Foo> obj = new Foo();  // ref count = 1
+//     return obj.Detach();
+//   }
+// };
+// typedef Ptr<Foo> FooPtr;  // common short-hand notation
+// FooPtr obj;
+// obj.Attach(Foo::CreatedInstance());  // ref count = 1
+// {
+//   FooPtr obj2 = obj;  // ref count = 2
+// }  // ref count = 1, obj2 out of scope
+// obj.Release();  // ref count = 0, object destroyed
+
+// Notes on usage:
+// 1. Virtual inherit from RefCount interface in base class if smart pointers
+//    are going to be defined.
+// 2. All RefCounted objects must be instantiated on the heap.  Allocating the
+//    object on stack will cause crash.
+// 3. Be careful when you have complex inheritance.  For example,
+//    class A : public RefCounted<A>;
+//    class B : public A, public RefCounted<B>;
+//    In this case the smart pointer is pretty dumb and don't count on it to
+//    nicely destroy your objects as designed. Try refactor your code like
+//    class I;  // the common interface and implementations
+//    class A : public I, public RefCounted<A>;  // A specific implementation
+//    class B : public I, public RefCounted<B>;  // B specific implementation
+// 4. Smart pointers here are very bad candidates for function parameters.  Use
+//    dumb pointers in function parameter list.
+// 5. When down_cast is performed on a dangling pointer due to bugs in code,
+//    VC++ will generate SEH which is not handled well in VC++ debugger.  One
+//    can use WinDBG to run it and get the faulting stack.
+// 6. Idioms for heap object as return value
+//    Foo* createFoo() { FooPtr obj = new Foo(); return obj.Detach(); }
+//    Foo* passthru() { FooPtr obj = createFoo(), return obj; }
+//    FooPtr end_scope_pointer;
+//    end_scope_pointer.Attach(passThrough);
+//    If you are not passing that object back, you are the end of scope.

+/**
+	A TiXmlHandle is a class that wraps a node pointer with null checks; this is
+	an incredibly useful thing. Note that TiXmlHandle 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
+	TiXmlElement* root = document.FirstChildElement( "Document" );
+	if ( root )
+	{
+		TiXmlElement* element = root->FirstChildElement( "Element" );
+		if ( element )
+		{
+			TiXmlElement* child = element->FirstChildElement( "Child" );
+			if ( child )
+			{
+				TiXmlElement* child2 = child->NextSiblingElement( "Child" );
+				if ( child2 )
+				{
+					// Finally do something useful.
+	@endverbatim
+
+	And that doesn't even cover "else" cases. TiXmlHandle addresses the verbosity
+	of such code. A TiXmlHandle checks for null	pointers so it is perfectly safe 
+	and correct to use:
+
+	@verbatim
+	TiXmlHandle docHandle( &document );
+	TiXmlElement* child2 = docHandle.FirstChild( "Document" ).FirstChild( "Element" ).Child( "Child", 1 ).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
+	TiXmlHandle handleCopy = handle;
+	@endverbatim
+
+	What they should not be used for is iteration:
+
+	@verbatim
+	int i=0; 
+	while ( true )
+	{
+		TiXmlElement* child = docHandle.FirstChild( "Document" ).FirstChild( "Element" ).Child( "Child", i ).ToElement();
+		if ( !child )
+			break;
+		// do something
+		++i;
+	}
+	@endverbatim
+
+	It seems reasonable, but it is in fact two embedded while loops. The Child method is 
+	a linear walk to find the element, so this code would iterate much more than it needs 
+	to. Instead, prefer:
+
+	@verbatim
+	TiXmlElement* child = docHandle.FirstChild( "Document" ).FirstChild( "Element" ).FirstChild( "Child" ).ToElement();
+
+	for( child; child; child=child->NextSiblingElement() )
+	{
+		// do something
+	}
