Changes between this version and 05q

- integrated Werner's patch

- debugged the glyph loader and the ttcalc component

- added full font viewing to 'view' as well as scaling and gray-levels.
  Now works well.. Try it !!
  ( Warning : locks up on certain fonts at very small sizes < 7 ).

- added a very simple debugger called 'fdebug'
  see note below on interpreter compilation.

- added a simple debugger shell within the interpreter. Compiled only when
  the DEBUG maco is defined ( required to compile fdebug )

- added a parameter to Load_TrueType_Glyph named 'allow_components'.
  if TRUE, enables the loading of composite glyphs; if FALSE, the
  load will always fail on composites.

  ( This was needed for the viewer, as composite glyphs hinting doesn't
    work yet ).

  Of course all test programs were modified to work well with these
  changes, with the exception of 'timer' ( on the todo list.. )

- enjoy the viewer, it's really nice :-) !!

  NOTE : There seem to be very, very, light differences with the Pascal
         viewer in the rendered glyphs. I'll take a deeper look at that
         problem with Pavel's debugger.
