  Fix alpha setting of WebGL contexts with SwANGLE on MacOS
  
  The emulation of the "alpha: false" setting was done with an
  RGBA format under the hood, which caused some unexpected
  results, which included non constant alpha values. Replacing
  GL_BGRA8_EXT with GL_BGRX8_ANGLEX solves this issue.
  
  This was discovered while debugging the following test:
  conformance/context/context-no-alpha-fbo-with-alpha.html
  but it may fix many other tests (I will update the
  expectations file after this fix rolls into Chromium)
