/**
* Called by {@link RenderManager} to render the geometry by

* The material is rendered as follows:

* <li>Determine which technique to use to render the material -
* either what the user selected via
* {@link #selectTechnique(java.lang.String, com.jme3.renderer.RenderManager)
* Material.selectTechnique()},
* or the first default technique that the renderer supports
* (based on the technique's {@link TechniqueDef#getRequiredCaps() requested rendering capabilities})<ul>
* <li>If the technique has been changed since the last frame, then it is notified via
* {@link Technique#makeCurrent(com.jme3.asset.AssetManager, boolean, java.util.EnumSet)
* Technique.makeCurrent()}.
* If the technique wants to use a shader to render the model, it should load it at this part -
* the shader should have all the proper defines as declared in the technique definition,
* including those that are bound to material parameters.
* The technique can re-use the shader from the last frame if
* no changes to the defines occurred.</li></ul>
* <li>Set the {@link RenderState} to use for rendering. The render states are
* applied in this order (later RenderStates override earlier RenderStates):<ol>
* <li>{@link TechniqueDef#getRenderState() Technique Definition's RenderState}
* - i.e. specific renderstate that is required for the shader.</li>
* <li>{@link #getAdditionalRenderState() Material Instance Additional RenderState}
* - i.e. ad-hoc renderstate set per model</li>
* <li>{@link RenderManager#getForcedRenderState() RenderManager's Forced RenderState}
* - i.e. renderstate requested by a {@link com.jme3.post.SceneProcessor} or
* post-processing filter.</li></ol>
* <li>If the technique {@link TechniqueDef#isUsingShaders() uses a shader}, then the uniforms of the shader must be updated.<ul>
* <li>Uniforms bound to material parameters are updated based on the current material parameter values.</li>
* <li>Uniforms bound to world parameters are updated from the RenderManager.
* Internally {@link UniformBindingManager} is used for this task.</li>
* <li>Uniforms bound to textures will cause the texture to be uploaded as necessary.
* The uniform is set to the texture unit where the texture is bound.</li></ul>
* <li>If the technique uses a shader, the model is then rendered according
* to the lighting mode specified on the technique definition.<ul>
* <li>{@link LightMode#SinglePass single pass light mode} fills the shader's light uniform arrays
* with the first 4 lights and renders the model once.</li>
* <li>{@link LightMode#MultiPass multi pass light mode} light mode renders the model multiple times,
* for the first light it is rendered opaque, on subsequent lights it is
* rendered with {@link BlendMode#AlphaAdditive alpha-additive} blending and depth writing disabled.</li>
* </ul>
* <li>For techniques that do not use shaders,
* fixed function OpenGL is used to render the model (see {@link GL1Renderer} interface):<ul>
* <li>OpenGL state ({@link FixedFuncBinding}) that is bound to material parameters is updated. </li>
* <li>The texture set on the material is uploaded and bound.
* Currently only 1 texture is supported for fixed function techniques.</li>
* <li>If the technique uses lighting, then OpenGL lighting state is updated
* based on the light list on the geometry, otherwise OpenGL lighting is disabled.</li>
* <li>The mesh is uploaded and rendered.</li>
