Force IPV4 for GDB remote debugging on Windows. Bind to localhost instead of unspecified address since listening on external ports probably isn't a good idea in the general case
|

Fix border rendering at end of line 1FE. vdp_inactive will probably need a small fixup for the edge case when we start between when the vcounter is incremented and the line is truly finished.
