/**
* Called by {@link RenderManager} to render the geometry by using this material.
*
* <p>The material is rendered as follows:
*
* <ul>
* <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.
* </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>{@link #getAdditionalRenderState() Material Instance Additional RenderState} - i.e.
* ad-hoc renderstate set per model
* <li>{@link RenderManager#getForcedRenderState() RenderManager's Forced RenderState} -
* i.e. renderstate requested by a {@link com.jme3.post.SceneProcessor} or
* post-processing filter.
* </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>Uniforms bound to world parameters are updated from the RenderManager. Internally
* {@link UniformBindingManager} is used for this task.
* <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.
* </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>{@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.
* </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>The texture set on the material is uploaded and bound. Currently only 1 texture is
* supported for fixed function techniques.
* <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>The mesh is uploaded and rendered.
* </ul>
* </ul>
