title: How to avoid antialiasing slits between shapes in NSView?
body: <p>I try to build some kind of ”triangular blends” based on the bezier paths. As far i got nice results, there is one problem I have no idea how to solve. 
  My shapes are build from hundreds of small triangles, each one is filled with RGBA colour. But between shapes is a visible slit, (probably) caused by antialiasing. With antialiasing off result is much worse.
  Does exist a way to ”tune” antialiasing in a NSView?
  Or some different approach?</p>
