  Vulkan: Add support for surface multisampling
  
  A multisample image is created for the surface if multisampling is
  enabled.  Prior to present, this multisample image is resolved into the
  swapchain image.
  
  FramebufferVk::readPixelsImpl similarly has got the ability to resolve
  the region of interest into a temporary image prior to readback.
  
  Tests are added to render a point, line and a triangle on a 4x
  multisampled surface.
