[magick-users] No border capture in snapshot using Import

> import with -frame options doesnt work with Compositing ON

It is likely that with compositing on, the window manager is using OpenGL to
paint the screen instead of X11.  The solution for proper screen capture
would be a program based on OpenGL rather than one like the IM import program
that is based on X11 API calls.
