      - Added Graph::ShadowCamera
      - Added PVRTC software decompressor

    Improvements:
      - Updated and build with Android Studio 3.0.1 and Android NDK 16.1.4479499
      - Improved Resource::PvrImage to support all the different PVR file
        format variants
      - Added filter options to Resource::Image for base & mip scaling

Version 1.00.6747Beta

    Changes:
      - Added new "--prescale_divisor" command line parameter to the 
        resource_packer tool, which is supposed to replace the existing
        (now deprecated) "--prescale_factor" parameter. When specifying 
        "--prescale_factor 1" together with "--check_config", the 
        resource_packer tool falsely includes all resources tagged with
        a prescale factor, instead only those for factor 1.
        For compatibility reasons, "--prescale_factor" still exists and
        behaves as before, but should be replaced with "--prescale_divisor"
        whenever possible.

      types and languages to be present in a single resource. Existing methods
      take an additional "shaderIndex" parameter to query a specific shader.
    - Removed the IEnums::ShaderLanguageVersion enumeration, which was merged
      into IEnums::ShaderLanguage.
    - Changed the Graph::IShader interface to allow returning video shader
      objects based on type (fragment/vertex), if present. Changed the
      Graph::Shader class to allow referencing shader resources containing
      both vertex and fragment shaders, and Graph::ShaderProgram to allow
      for referencing such a shader node via the common "shaderId" attribute.

  New Features:
    - Added a fallback mechanism to Graph::IShader and Graph::IProgram, used
      in case a shader/program fails to compile or link.

      Murl::Addons::Filepanel, Murl::Addons::Openmax and Murl::Addons::Vuforia.
      To adjust existing code simply replace all '*' by 'Ptr',
      e.g. Addons::Facebook::IAddon* to Addons::Facebook::IAddonPtr.
    - Changed Murl::IAppAddonRegistry class interface methods to accept
      IAddonPtr shared pointers only.
    - Changed vuforia addon graph nodes XML namespace:

    - Changed addon libraries to separate files for each addon on all
      supported platforms.

      GetEnumValueByName(), GetEnumName() to GetEnumNameByValue(), and
      IsEnumAvailable() to IsEnumValueAvailable(). Added methods to query
      values/names by index.
    - Cleaned up enum definition macros in murl_enum.h
    - Allow multiple controllers per node (see Graph::INode::AddController()
      and related methods). In addition to specifying a single node controller
      by e.g. controller.animationResourceId="...", it is possible to create
      multiple controllers via XML by defining a trailing index after the
      "controller" attribute part, e.g. controller.0.animationResourceId="..."
      and controller.1.scriptResourceId="..."

  New Features:
    - Lua addon: Adds a wide-ranging integration of the Murl framework

      and IEnums::FEATURE_INDEX_BUFFER_FORMAT_UINT32.
    - Added HLSL shader support in DirectX9 renderer (SM 2.0/3.0)
    - Added cube map support for DirectX 9.0 and 11.1
    - Introduced the IEnums::ShadowVolumeGenerationMode enumeration, used
      in Graph::ResourceShadowGeometry.
    - Added support for multi targets in Vuforia addon.
    - Introduced resource path notation analogous to scene graph node paths.
      In addition to the existing "packageId:resourceId" scheme, it is possible
      to specify a resource ID as e.g. "/packageId/resourceId". If a resource
      is referenced from a sub-graph that was also created from a graph
      resource, it is possible to also use relative paths. In other words,
      a Graph::FlatTexture node may specify its image resource without explicit
      package ID when the image is in the same package as the graph resource.
    - Added culling option for Graph::BoundingBox nodes
    - Added SetBufferAccessMode() to Graph::IDrawable interface and all

      IEngineConfiguration::SetDefaultMaxTextureAnisotropy() and
      Graph::ITexture::SetMaxAnisotropy()

      in OpenGL or D3DRS_DEPTHBIAS/D3DRS_SLOPESCALEDEPTHBIAS in DirectX 9

      method

      explicitly specifying an index (such as textureSlot.0="42"), which
      defaults the index to 0. Applicable on various nodes that define
      attributes in an analogous way (single vs. plural attribute names),
      such as Graph::Clip (timelineId/timelineIds) or Graph::Material
      (textureStage/textureStages).

    - Misc logic fixes


Version 1.00.2096Beta

  Important API Changes! You should perform a search&replace operation on your
  user code in order to incorporate these changes.
    - Renamed Murl::ISystemFont to Murl::IFont
    - Unified font attribute names in Graph::TextGeometry and FlatTextTexture,
      and moved all respective methods to Graph::IFont interface:
      "systemFontId","fontId" -> "systemFontName"
      "systemFontSize" -> "fontSize"
      "systemFontTextColor" -> "textColor"
      "systemFontBackgroundColor" -> "backgroundColor"

  Improvements:
    - Added Truetype and OpenType font embedding support through font_converter
      and Graph::TextGeomety/Graph::FlatTextTexture
    - Added border/borderX/borderY attributes to Graph::PlaneGeometry,
      PlaneSequenceGeometry, TextGeometry and Button, for better content
      alignment, plus respective interface methods
    - Added IAppConfiguration::SetSystemDebugInfoItems() to select statistic
      items to display when the debug package is loaded
    - Added posX/posY and sizeX/sizeY attributes to Graph::Camera nodes, to
      select only a sub-region of the output surface to render to
    - Physics simulator cleanup & improvements
    - Added "scale" attribute to XML animation files, to set a unified scale
      factor for all 3 axes
    - Added Logic::ITimeline::SetCurrentTime() and SetCurrentLoop() methods
    - Stripped unnecessary debug information from (most) static libs

  Minor fixes:
    - Fixed Graph::Camera to consider scissor mask when clearing
    - Fixed minor memory leaks
    - Fixed a crash in Graph::TextGeometry when using a prescale factor other
      than 1
    - Fixed a misbehavior in Graph::TextGeometry when re-setting text
    - Unified QueryTextSize() in Graph::TextGeometry and FlatTextTexture
      to always return _unscaled_ values
    - Fixed system font rendering on OSX/IOS (position/cropping issues)
    - Fixed system fonts to accept a user-defined leading value
    - Fixed string-to-color conversion to set alpha to 100% when not explicitly
      specified via a single-value hex string
    - Container classes: Minor fixes for ObjectArray/ObjectIndex/ObjectMap

      in ALL locic interfaces and classes
    - Renamed Identity() to SetIdentity() for Math::Matrix
    - Renamed Minimum()/Maximum()/MinimumSelf()/MaximumSelf() to Min()/Max()/
      MinSelf()/MaxSelf() for Math::Vector
    - Renamed Length()/LengthSquared() to GetLength()/GetSquaredLength() for
      Math::Vector
    - Removed GetLocalEventVelocity() and GetLocalEventAcceleration() for
      Graph::IButton

    - Added Graph::IAligner interface and Graph::Aligner node
    - Added Graph::BoxCuller for orthographic cameras
    - Added system font rendering capability for Graph::TextGeometry
    - Enabled dynamic texture size change
    - Enabled Non-power-of-two textures, if enabled by GPU
    - Added IEnums::FEATURE_LIMITED_NON_POWER_OF_TWO_TEXTURES and
      IEnums::FEATURE_FULL_NON_POWER_OF_TWO_TEXTURES engine features
    - Added Math::E constant and Math::Log2()/Math::Log10() functions
    - Improved error handling for textureSlot attribute in geometry nodes
    - Added DepthOrderKey element for XML animation resources
    - Added Util::StringToXXArray() methods
    - Enabled aspect clipping/borders in Graph::Camera nodes
    - Added Logic::ITimeline::IsOrWasRunning() method
