## Detailed Description

The Effect type combines a set of techniques and parameters used by those techniques to produce a rendering effect for a material.

An Effect instance should be shared among several Material instances when possible.

A Parameter defined on an Effect is overridden by a QParameter (of the same name) defined in a Material, TechniqueFilter, RenderPassFilter.

      Effect {
          id: effect

          technique: [
              Technique {
                  id: gl3Technique
                  graphicsApiFilter {
                      api: GraphicsApiFilter.OpenGL
                      profile: GraphicsApiFilter.CoreProfile
                      majorVersion: 3
                      minorVersion: 1
                  }
                  renderPasses: [
                      RenderPass {
                          id: gl3Pass
                          shaderProgram: ShaderProgram {
                              ...
                          }
                      }
                  ]
              }
          ]
