Canvas::Path: reduce number of OpenGL state changes.

 - Do not enable any multisampling as for FBOs it is not
   supported anyhow.
 - Just restore GL_BLEND and GL_STENCIL_TEST manually
   => Getting rid of the huge load of glPushAttrib/glPopAttrib
      gets us a huge performance boost, especially for drivers
      with slow state stack implementations.
