[VXA] Map Resolution Glitch Fix v1.0

#===============================================================================
# Map Scroll Glitch Fix v1.0 by wltr3565 (RMVX ACE only)
#
# In widescreen resolution (640x360) the bottom of the map shows up some upmost
# part of the map. This one fixes this.
# But it's only for 640x360 for now, so if there's need for fixing in many
# aspects, let me know. It's rare for an RM game to have a different resolution
# other from either 544x416 or 640x480.
#
# Just paste this above main, and as above as possible above other custom
# scripts.
