D23504: [platforms/x11] Remove triple buffering detection

[Fredrik Höglund]

fredrik added a comment.


  This code doesn't actually have anything to do with triple-buffering. Its sole function is to detect whether glXSwapBuffers() blocks; the (incorrect) assumption being that if it doesn't, then the driver uses triple-buffering.
  But this information is only used to decide whether to call glXSwapBuffers() in prepareRenderingFrame() or endRenderingFrame(). KWin doesn't try to render more than one frame per swap interval regardless.
