+ // GlueGen converts C types like int** into Java arrays of direct
+ // buffers of the appropriate type (like IntBuffer[]). If the tool
+ // supported conversions like byte[][] -> char**, it would
+ // effectively be necessary to copy all of the data from the Java
+ // heap to the C heap during each call. The reason for this is that
+ // if we wanted to use GetPrimitiveArrayCritical to lock down the
+ // storage for each individual array element, we would need to fetch
+ // each element of the two-dimensional Java array into temporary
+ // storage before making the first GetPrimitiveArrayCritical call,
+ // since one can not call GetObjectArrayElement inside a Get /
+ // ReleasePrimitiveArrayCritical pair. This means that we would need
+ // two top-level pieces of temporary storage for the two-dimensional
+ // array as well as two loops to set up the contents, which would be
+ // too complicated.
+ //
+ // The one concession we make is converting String[] -> char**. The
+ // JVM takes care of the C heap allocation for GetStringUTFChars and
+ // ReleaseStringUTFChars, and this conversion is important for
+ // certain OpenGL operations.
