Subject: [PATCH] Applied patch from Tomaz Solc fixing a bug in the
 CenterDisplay function.

This patch fixes a bug in the CenterDisplay function that doesn't do a
RestoreCrosshair() after HideCrosshair().

This causes the crosshair stack overflow when using the DRC checker (which
calls CenterDisplay a lot).

Minor re-indentation by Peter Clifton during application.
