GHOST/Wayland: draw a software-cursor when wrapping cursor motion

As Wayland doesn't support moving the cursor, draw a cross-hair cursor
at the location used by Blender.

Without this, the cursor was locked at the location where grab started,
making some actions unusable since the cursor location was invisible.
