-//! Compatibility layer for old OpenGL without VBO.
-//! Make sure to pass pointer from GetDataOffset() instead of NULL.
-//! Method GetDataOffset() returns pointer to real data in this class
-//! (while base class OpenGl_VertexBuffer always return NULL).
-//!
-//! Methods Bind()/Unbind() do nothing (do not affect OpenGL state)
-//! and ::GetTarget() is never used.
-//! For this reason there is no analog for OpenGl_IndexBuffer.
-//! Just pass GetDataOffset() to glDrawElements() directly as last argument.
-//!
-//! Class overrides methods init() and subData() to copy data into own memory buffer.
-//! Extra method initLink() might be used to pass existing buffer through handle without copying the data.
-//!
-//! Method Create() creates dummy identifier for this object which should NOT be passed to OpenGL functions.
