// Normally SCI cuts the character and draws the part that fits, but the common SJIS doesn't support that
// It seems as if the PC98 ROM actually uses the given position as the center of the character, that's why we
// subtract 4 here. Otherwise the characters will be slightly to the right. The actual cause for "bad" coordinates
// is GetLongest() inside GfxText16. It leaves the last character that is causing a split to a new line within the
// current line instead of removing it. That way the result will actually be too long (not our fault, sierra sci
// does it the same way)

// According to LordHoto the PC98 ROM actually split the screen into 40x25 kanji chars and was only able to place
// them there. So removing the lower 4 bits of the horizontal coordinate puts them into the correct position (it seems).
// If we don't do this, the characters will be slightly to the right, caused by "GetLongest()" inside GfxText16 that
// leaves the last character that is causing a split into a new line within the current line instead of removing it.
