  c/utils:
  - Extend compute_overlay_pos so that it will check for any windows infront of the overlay and crop the displayed area as appropriate. The algorithm is simple (only checks one window at a time, so a set of windows which collectively form a full edge won't cause cropping), but it's better than nothing, especially when dealing with Basic overlays, which always appear ontop of the desktop. In particular, this fixes the bug where a Basic overlay from an iconised window will still be visible, due to the window technically still being open (it's just been moved behind the pinboard)
  - Also add/improve source comments, and fix STACK_PUSH setting the wrong next-chunk pointer when allocating a new stack frame
  doc/GraphicsV:
  - Specify the correct number of the min. screen banks mode variable
