 '''001792a4 - 001793fc'''
 
 '''Parameters''' : r4 = Target Tile Height (height * 2 + halves + depht *2)
              r5 = Ability vetical tolerance (Vertical in pacher)
              r6 = 0x01 if Ability has the top-down flag
  
 Nullify some targetable panels AoE flag and targetd flag is they don't match the ability vertical tolerance.
 If both elevation are in the AoE, the nearest tile only will be checked (the other one is "discarded")

=== Notes ===
 In thoses notes Tile refers to data stored at 0x8018f8cc, panel refers to data stored at 0x80192dd8
 
 Loop through all XY coordinates (0x100 iteration), lower and higher elevation Tiles are checked in each iteration.
 The flags of lower and higher targetable panels are nullified if necessary (matching the tile ID during each iteration)
  
 - Check if tile is selectable (via Tile [0x06] byte), if not matching panel AoE and targeted flags are nullified
 - If the ability has the top down flag, and the higher elevation tile is selectable, the lower panel is nullified
 - Check the Height distance between lower and higher elevation tiles and the targeted tile, discard the more distant one
 - Check of Height distance is greater than vertical tolerance, if so, nullify AoE and Targeted flag of the panel
