Changes in version 5.02:

2006-06-04	Michael Gogins	<gogins at pipeline.com>
	* Changed the MIDI interoperability opcodes (OOps/midiinterop.c)
	midinoteoncps, midinoteonoct, midinoteonpch to leave key and
	velocity unchanged for score-driven performance.

2006-06-04	Istvan Varga	<ivarga at csounds.com>
	* Engine/otran.c:
	  work around constndx() not being compiled correctly

2006-06-03	Istvan Varga	<ivarga at csounds.com>
	* Engine/fgens.c, InOut/libsnd_u.c, OOps/diskin.c, OOps/diskin2.c:
	  GEN01, diskin, diskin2, soundin: with an iformat value of -1,
	  reject headerless files, rather than assuming the same format
	  as the one specified on the command line
	  GEN01: added format codes 7 (8 bit unsigned), 8 (24 bit), and
	  9 (doubles)
	* Engine/entry1.c, H/sndinfUG.h, OOps/sndinfUG.c:

	  defaults to 1, and if zero, will make the opcodes return zero on
	  headerless files rather than some possibly incorrect defaults

2006-04-29	Istvan Varga	<ivarga at csounds.com>
	* Made it possible to control the behavior of the FLTK plugin
	  from the host application. This can be done with the following
	  code between calling csoundPreCompile() and csoundCompile():
	    CSOUND *csound;
	    ...
	    csoundCreateGlobalVariable(csound, "FLTK_Flags", sizeof(int));
	    *((int*) csoundQueryGlobalVariable(csound, "FLTK_Flags")) = flags;
	  where 'flags' can be the sum of any of the following values:
	    1: disable widget opcodes
	    2: disable FLTK graphs
	    4: disable the use of a separate thread for widget opcodes
	    8: disable the use of Fl::lock() and Fl::unlock()
	   16: disable the use of Fl::awake()
	  additionally, after calling csoundCompile(), the same variable
	  can be checked to find out if graphs or widget opcodes are used:
	   32: FLrun opcode was called
	   64: callbacks for FLTK graphs are set
	* Top/main.c:
	  fixed crash on registering opcodes from the host application
	* frontends/fltk_gui:
	  new GUI frontend that uses the Csound 5 API and FLTK

	* Engine/entry1.c: Added remove opcode.  Probably should be an API
	function rather than opcode

	* Engine/insert.c (delete_instr): New code to delete non-active
	instruments.  Still needs to be checked as it may leave structures
	dangling.

2006-04-15	Istvan Varga	<ivarga at csounds.com>

	  - added new classes to wrap MIDI I/O:
	      CsoundMidiInputStream     sends MIDI input messages
	      CsoundMidiOutputStream    polls MIDI output messages
	  - added MIDI I/O callbacks to CsoundCallbackWrapper
	  - made it possible to use the message buffer in multiple threads,
	    to allow for redirecting the message output of a
