  Texture: Pass ImageIndex to relevant methods.
  
  The Vulkan back-end will be using this helper struct, so make it
  available everywhere. This cleans up a lot of the code for D3D.
  
  Potentially in the future we could generate these in the entry
  points if we supported packing multiple arguments into one.
  
  Also changes a few parameter types to GLint for compatibility.
  
  Also updates the Vulkan Texture implementation check the stored
  vk::Format on setImage changes.
