  <h4>GlueGen Internal Alignment for Compound Data</h4>
  In general, depending on CPU and it's configuration (OS), alignment is set up 
  for each type (char, short, int, long, ..).
  <p>Compounds (structures) are aligned naturally, i.e. their inner components are aligned<br>
  and are itself aligned to it's largest element.</p>
  See:<br>
  <ul>
   <li><a href="http://en.wikipedia.org/wiki/Data_structure_alignment">Wikipedia Data Structure Alignment</a></li>
   <li><a href="http://en.wikipedia.org/wiki/Data_structure_alignment#Data_structure_padding">Wikipedia Data Structure Alignment - Padding</a></li>
   <li><a href="http://www.viva64.com/en/l/0021/">Viva64 Data Alignment</a></li>

  </ul>
  
  <h5>Simple alignment arithmetic</h5>
  Modulo operation, where the 2nd handles the case offset == alignment:
  <blockquote>
    padding = ( alignment - ( offset % alignment ) ) % alignment ; <br>
    aligned_offset = offset + padding ;
  </blockquote>
  Optimization utilizing alignment as a multiple of 2 <code>-> x % 2n == x & ( 2n - 1 )</code><br>
  <blockquote>
   remainder = offset & ( alignment - 1 ) ; <br>
   padding = ( remainder > 0 ) ? alignment - remainder : 0 ;<br>
   aligned_offset = offset + padding ;   
  </blockquote>
  Without branching, using the 2nd modulo operation for the case offset == alignment:
  <blockquote>
   padding = ( alignment - ( offset & ( alignment - 1 ) ) ) & ( alignment - 1 ) ;<br>
   aligned_offset = offset + padding ;   
  </blockquote>
  See <code>com.jogamp.gluegen.cgram.types.SizeThunk.align(..)</code>.
  
  <h5>Type Size &amp; Alignment for x86, x86_64, armv6l-32bit-eabi and Window(mingw/mingw64)</h5>
  Runtime query is implemented as follows: 
  <pre>
   typedef struct {
     char   fill;  // nibble one byte
                   // padding to align s1: padding_0 
     type_t s1;    // 
   } test_struct_type_t;
  
             padding_0 = sizeof(test_struct_type_t) - sizeof(type_t) - sizeof(char) ;
   alignmentOf(type_t) = sizeof(test_struct_type_t) - sizeof(type_t) ;
  </pre>

  <h4>GlueGen Platform Header Files</h4>
  GlueGen provides convenient platform headers,<br/>
  which can be included in your C header files for native compilation and GlueGen code generation.<br/>
  <br/>
  Example:<br/>
  <pre>
   #include &lt;gluegen_stdint.h&gt;
   #include &lt;gluegen_stddef.h&gt;
 
   uint64_t test64;
   size_t size1;
   ptrdiff_t ptr1;
  </pre>
  <br/>
  To compile this file you have to include the following folder to your compilers system includes, ie <code>-I</code>:<br/>
  <pre>
    gluegen/make/stub_includes/platform
  </pre>
  <br>
  To generate code for this file you have to include the following folder to your GlueGen <code>includeRefid</code> element:<br>
  <pre>
    gluegen/make/stub_includes/gluegen
  </pre>
  <h4>GlueGen Pre-Defined Macros</h4>
  To identity a GlueGen code generation run, GlueGen defines the following macros:<br/>
  <pre>
     #define __GLUEGEN__ 2
  </pre>
