IS VIRTUAL TEXTURE MANAGEMENT ENABLED This function will check whether the virtual texture management mode is enabled.
Syntax
    isEnabled = ENABLE VIRTUAL TEXTURE MANAGEMENT()
Returns
Returns true if virtual texture management is enabled, or false otherwise.
Description
Virtual texture management is required by certain third party plugins that depend on obsolete resource management functionality built into DirectX9.0c but that was removed for efficiency reasons in DirectX9Ex. It is disabled by default and can be enabled by calling the ENABLE VIRTUAL TEXTURE MANAGEMENT command. This function is merely a convenience function to check whether that function has been called without a corresponding call to DISABLE VIRTUAL TEXTURE MANAGEMENT inbetween. Take note that unless you're using a plugin that requires it (such as DarkVIDEO) you will want to leave this disabled as it will otherwise result in redundant image copying and pixel transfer operations behind the scenes.
