  Add new GL_RGBX8_ANGLEX format
  
  Currently, IOSurface objects using {GL_RGB, GL_UNSIGNED_BYTE}
  are natively represented with GL_BGRX8_ANGLEX, which we use
  instead of other RGBA formats in order to avoid issues when
  a canvas uses 'no alpha':

  This unfortunately causes some other issues because of the
  implicit RGB <-> BGR conversion like type mismatches in
  subresource updates. This CL adds a new type, RGBX8, which
  will be usable by IOSurface objects and which behaves exactly
  like the BGRX8 format with the B and R channels flipped.
