Modified Tutorial04: introduced recommended drawing approach with arbitrary number of [command buffer, semaphore, fence] resources and command buffer recorded each frame; removed creation of a custom image and a copy operation (from custom image to swapchain); framebuffer is now created only during command buffer recording; added dynamic viewport and scissors test states.
