Crash with vid_640x400 and a Border
Join a game and hit - to make the screen have a green border, then apply vid_640x400 and odamex will crash.
r_plane.cpp:265 is where it crashes
still happens with SDL2 on January 5, 2019 with latest master
This has been resolved in the 0.8.3 release candidate.
The global variable ST_Y is not correct when vid_320x200 or vid_640x400 is enabled, which causes the border drawing function to write past the end of the screen buffer. The function ST_StatusBarY() provides the correct value for top edge of the status bar.
