Development Version 0.6.9-4

Starting from this version, the tar-ball distribution is separated into two files: source & documentation tar-ball and media tar-ball. The media tar-ball is expected to change much rarely than the source & documentation tar-ball.

[INCOMPATIBLE CHANGES] Many of the symbols/features which have been deprecated in the previous version are removed :
- These deprecated functions from the CEventHandlerBase class have been removed :
  - virtual void EventKeyPress(EKeySymbol eKeySym)
  - virtual void EventKeyRelease(EKeySymbol eKeySym)
  - virtual void EventButtonPress(EBtnSymbol eButtonSym)
  - virtual void EventButtonRelease(EBtnSymbol eButtonSym)
  - virtual void EventMouseMove(int32_t n32XPos, int32_t n32YPos)
  Overriding those function will cause the application to become not responding to any keyboard and mouse button events.
- The deprecate function CVideoEnv::InputBox() has been removed.
- The function CParticle2DNE::Initialize() which take a C3DEnv* as one of its parameter has been removed.
- The functions for saving to older file formats have been removed :
  - CPanel3DBuffer::__SaveVPD100()
  - CPanel3DBuffer::__SaveVPD110()
  - CPanel3DBuffer::__SaveVPD111()
  - CImageBuilder::__SaveVIB100()
  - CImageBuilder::__SaveVIB110()
- The _C, _T, C, and T prefixes for classes and structures have been removed. Some classes and structures are also renamed. For backward compatibility, typedefs or #defines are provided for existing classes and structures. However, new classes and structures will not be typedef-ed.
- See the topic "Converting from Older Version of VortexGE" for further information concerning this matter.
Video environment changes and/or improvements :
- [COULD BE INCOMPATIBLE CHANGES] The function CDialogPage::GroupRadioButtons() now automatically checks the first radio button in the list. See the topic "Converting from Older Version of VortexGE" for further information concerning this matter.
- A new function, CDialogPage::CheckRadioButton() was added. This function can be used by all derivative classes of CDialogPage to check a radio button while unchecking all other radio buttons in the same group. Calling this function is more preferred than calling CRadioButton::SetValue().

Audio environment changes and/or improvements :
- Added the support for streaming sound buffer (currently only support Ogg-Vorbis).
Other changes and/or improvements :
- VortexGE should be correctly built using GCC 4.2.x and GCC 4.3.x (some compilation warnings may occur). Note that the path to the new libstdc++ shared library file ("libstdc++.so.6.0.9" or "libstdc++.so.6.0.10") needs to be added to the LD_LIBRARY_PATH environment variable in order to run the resulting applications.
- Lua 5.1.4 is now used as the scripting engine backend.
- Some code cleanups and bug fixes.
- Some improvements in the configuration script.
