Graphic3d_CLight::ToCastShadows() - added new property defining if light should cast shadows (ignored by Ray-Tracing). OpenGl_ShaderManager::stdComputeLighting() now implements shadow mapping for directional lights. OpenGl_ShaderManager::prepareGeomMainSrc() now handles copying of arrays. OpenGl_Context::ShadowMapTexUnit() - added property defining an offset for shadow map texture units. OpenGl_ShadowMap - added new class storing shadow map FBO with parameters. OpenGl_View::prepareFrameBuffers() - added resizing of shadow map FBOs. OpenGl_View::Redraw() - added section redrawing scene into shadow map FBOs via OpenGl_View::renderShadowMap() method. vrenderparams - added new parameters -shadowMapResolution and -shadowMapBias.
