rotate tk canvas

Hallo,

i have a tk canvas and want to rotate all its objects (there are
many objects because i draw a country map). Because it
must be very fast i am searching for a performant solution,
propably an API like openGL ore something like that which
can take a X11 pixmap and rotate it for me.

I have no idea, this is an absolutely new theme for me.

Thanks

.
