  Message : Vulkan: Rename format fields. Renames 'angleFormat' to 'intendedFormat'. Also renames 'bufferFormat' and 'imageFormat' to 'actualImageFormat' and 'actualBufferFormat'. This renaming should make it clearer to the reader what the meaning of the different format fields are. Intended format is the front-end format and the actual formats are the formats we pass to Vulkan. Also updates the documentation.

• # ANGLE: Vulkan Back-end
  
  ANGLE's Vulkan back-end implementation lives in this folder.
  
  [Vulkan](https://www.khronos.org/vulkan/) is an explicit graphics API. It has a lot in common with
  other explicit APIs such as Microsoft's [D3D12][D3D12 Guide] and Apple's
  [Metal](https://developer.apple.com/metal/). Compared to APIs like OpenGL or D3D11 explicit APIs can
  offer a number of significant benefits:
  
   * Lower API call CPU overhead.
   * A smaller API surface with more direct hardware control.
   * Better support for multi-core programming.
   * Vulkan in particular has open-source tooling and tests.

  ## Back-end Design
  
  The [`RendererVk`](RendererVk.cpp) class represents an `EGLDisplay`. `RendererVk` owns shared global
  resources like the [VkDevice][VkDevice], [VkQueue][VkQueue], the [Vulkan format tables](vk_format_utils.h)
  and [internal Vulkan shaders](shaders). The [ContextVk](ContextVk.cpp) class implements the back-end
  of a front-end OpenGL Context. ContextVk processes state changes and handles action commands like
  `glDrawArrays` and `glDrawElements`.
  
  Implementation details can be found in the `doc` directory.
