The ShaderBinder class can be used for the case that a block of code should be executed with a given Shader being bound. This is useful for all the cases where there is a if-block for OpenGL2 execution with a Shader being pushed in the first line to the ShaderManager and popped in the last line of the block. With the helper this can be simplified to: ShaderBinder binder(myCustomShader); or ShaderBinder binder(ShaderManager::GenericShader); The ctor of ShaderBinder pushes the given Shader to the stack and once the helper goes out of scope it will be popped again from the stack. In addition the helper can take care of OpenGL 1 compositing, that is it just does nothing. So it can also be used where there is a shared OpenGL1 and OpenGL2 code path where the Shader should only be pushed in OpenGL2. This basically removes all the checks for the compositing type before pushing/popping a Shader to the stack. REVIEW: 106521
