  Vulkan: Improve Bresenham line emulation.
  
  Clamps the vertex position to the subpixel grid before interpolation.
  This will give more correct results on systems that have less than
  8 bits of subpixel accuracy.
  
  Also uses a more accurate formulation for the emulation filter in the
  fragment shader using dfdx and dfdy.
  
  Fixes line raster CTS tests on SwiftShader. Still does not produce spec
  conformant lines. Updates the public docs to indicate this.
