Replace the canvas_t type with a struct canvas which should in the
long run hold all state (position, dimension, backing store,...) about
the map canvas and so making it accessible to the common code.

Add a gui-dependent struct canvas_store which is opaque in the common
code.

Patch by Jason Short.
