2002/01/02 Martin Dudok van Heel (nldudok1@olifantasia.com)-- ported to win32. 
     qtlookat.pro was changed and a few peaces of unix/X11 dependend code were changed.
     Also now the new name OpenVrml is used for the includes (was vrml97). It should
     still work on unix systems but this is not yet tested.
2000/04/06 ken bentley -- used the method in gtklookat wsPostRedraw to fix the
     event loop problem for the plugin--the trade-off is that animation stops
     when the cursor leaves the window--but that's still a huge improvement.
2000/04/02 ken bentley -- plugin changes. rewrote loadCB (piInstance.cpp) to use
     zlib; now zipped wrl's work in the plugin. Added a bunch of debugging code
     to get around Netscape's suppression/truncation of stderr, stdout. Now textures
     get read through the plugin coming from System::httpFetch() but they still fail.
     Still lack the big picture, but when the textures come in I'm sending them
     through VrmlScene::loadFromFunction just like wrl's--which routes them thru the
     parser--Looks like Image.cpp want's a local file to pngread--I can pass a local
     file from netscape cache, but don't know where to pass it? Event loop in the
     plugin still hangs on slow systems (means its wrong). 
     renamed qInstance to piInstance--Qt lib has a class qInstance.

2000/03/31 bentley -- major overhaul of plugin code. This work is with Qt 2.1-beta3
      still not stable, but closer to sane. Still have event loop problems to work out
      between Qt and Netscape.  Borrowed some code from Chris Morley's xmplugin to talk
      to libVRML97 via VrmlScene::loadFromFunction.

    o bentley -- updated all sources macros, and documentation files for release
      of 0.8.1 tarball. This is the first release in tarball form. Syncing with
      libVRML97 version number for this releas only. QtLookat's version number will
      increment independantly from here on.
    o The plugin build has been disabled for this release. All the tools are still
      there, they are disabled because this release will go on the X3D SDK CD, 
      and the plugin is not really stable enough for that arena yet.

    o Ken Bentley -- many mods to make plugin behave with Qt 2.0.2. It now works
      if 1 line is commented out of $QTDIR/src/kernel/qnpsupport.cpp. Have notified
      Troll Tech (but I sent it to qt-interest, may resend to qt-bugs). Haven't heard
      back yet. (It works on simple wrls, that is). Still need to resolve how to link
      theSystem to individual plugin instances. Then override System::httpFetch to 
      correctly fetch textures and sounds through the pluginInstance interface.

    o Troll Tech recommends using snapshots until Qt 2.1 is released. They say the
      plugin extension will be fixed by then. In the meantime, there's also the not
      recommended option of commenting out 1 line in the Qt sources as a work around.
      
    o Added mime types for compressed files to plugin --.wrz, .wrl.gz
