  Vulkan: Fix copySubImageImplWithDraw() for pre-rotation
  
  This involves cases of copying from a rotated default framebuffer.
  Various adjustments are needed for where the source is and its
  relationship to gl_FragCoord in the custom ImageCopy fragment
  shaders.  Various tests are affected, including the following:
  
  Test: angle_deqp_gles2_tests --gtest_filter=dEQP.GLES2/functional_texture_specification_basic_copy*teximage2d_*
  Test: angle_deqp_gles3_tests --gtest_filter=dEQP.GLES3/functional_texture_specification_basic_copy*teximage2d_*
