  Vulkan: Add OpenGL line segment rasterization.
  
  Line rasterization rules are implemented using a shader patch. The
  patch does a small test and discards pixels that are outside of the
  OpenGL line region.
  
  The feature is disabled on Android until we can determine the root
  cause of the test failures.
  
  Bug: angleproject:2598
