Log Message:
-*- Fixed a error in inifile.cpp. The array allocated with new[] was
    realloc()'ated. Now it is new/memcpy/delete'd.

-*- Fixed a minor memory leak in system driver. Event cords weren't deleted
    at shutdown.

-*- Fixed a bad error in inifile.cpp triggered by [Macintosh] section in
    vfs.cfg: the loader switches to base64 mode due to empty assignments like:

    HOME =

    (such lines are used to denote base64 keys) and then doesn't switch back
    when it detects invalid base64 symbols. I changed the ini loader so that
    it switches to base64 mode by '==' statement, e.g.:

    HOME ==
    ODAwMDAwMDAgd2hpbGUKICAgIHNoYXJlZCBs
    aWJyYXJpZXMgdXN1YWxseSBoYXZlIGFkZHJl
    c3NlcyBsaWtlIDB4NHh4eHh4eHgpLgo=
    ===
    ;/HOME

    If you want to assign the '=' value to a key, insert a space, e.g:

    HOME = =

    is interpreted as a normal key, not the head of a base64 stream.
    csIniFile::Save() inserts spaces automatically, thus a saved ini file
    should read perfectly. Also if something other than newline follows the
    second equal sign, it is also interpreted as a normal key.

-*- Fixed a few memory leaks in MazeD.

-*- Finished material manager dialog. Now it is functional, use Ctrl+m to
    invoke it, model manager has moved to Ctrl+M. Fixed several bugs that
    leads to MazeD crashes related to materials.

-*- Fixed a bad bug in common texture manager object (txtmgr.cpp): the
    constructor did no CONSTRUCT_IBASE.

-*- I have enhanced the memory debugger so that on Linux and OS/2 it is able
    to debug malloc/realloc/free's as well as new's and delete's. There is a
    drawback on Linux though: it will intercept all malloc/free's from all
    dynamic libraries (even from libX11.so) thus you will see a lot of memory
    leaks belonging to other libraries (notably libc and libX11). You can
    filter them by address (in Linux program address is > 0x80000000 while
    shared libraries usually have addresses like 0x4xxxxxxx). If you want
    to debug memory leaks in plug-ins, build executable in static link mode.

-*- Fixed a memory leak in csfont plug-in.

-*- By the way, Crystal Space currently consists of about 350.000 lines
    of code :-)

-*- Rearrangement of some aspects of the texture manager to simplify interface
    API for textures and materials. Previously you had to call texture manager's
    RegisterXXX (where XXX is Texture or Material) then you had to call
    PrepareXXX to force texture manager recompute the internal representation
    of the texture/material; when you are done you had to call UnregisterXXX.
    Now it works a little different: by calling RegisterXXX you create a new
    texture/material handle, and further you work only with that handle:
    call handle->Prepare() to prepare texture or material for usage; call
    handle->DecRef() enough times to destroy the handle (you don't have to
    call UnregisterXXX anymore).

    I have fixed all the 3D renderers for this, however I'm not sure about
    Direct3D and Glide renderers (haven't compiled them). All others are
    fully functional.

    You can still call PrepareTextures() and PrepareMaterials() on texture
    manager object to call Prepare on all objects at once.

-*- Renamed csTextureMMSoftware into csSoftwareTextureHandle and csTextureMM
    into csTextureHandle for cleaner names.

-*- Before closing the system (System::Close) the engine will free all texture
    and material handles since after closing the graphics driver the handles
    become invalid no matter whenever we did IncRef or not.

-*- Implemented alpha textures support for DrawPolygon, DrawPFX and DrawPixmap
    in OpenGL renderer.

-*- Re-worked OpenGL texture cache. Texture unloading happens now in a
    centralized routine, which minimizes the effort required to fix any
    bugs in it (one of which was causing SIGSEGV on exit).
