Descriptive Problem Summary:

Setting map zoom to a high value and having HUD objects outside of normal bounds (e.g. screen_loc="0,0", screen_loc="EAST+2,NORTH+1") causes the non-HUD part of the map to clip incorrectly when the map is zoomed in enough to overflow the control.

Numbered Steps to Reproduce Problem:

1) Add a screen object to screen_loc="0,0".
2) Do the same for "EAST+2,NORTH+1".
3) Use winset to set the map control's zoom to a high number like 4.

Expected Results:

The map should zoom in, causing blackness around the edges to vanish as the zoom gets higher and the HUD objects are pushed out of view.

Actual Results:

The HUD objects are pushed out of view as expected, but the non-HUD parts of the map are clipped at the right and bottom of the control. The amount of this clipping worsens as the zoom increases.
