Text markers stop renders outside the camera

Text from BgText will stop rendering if the marker goes too far off-screen. This is most obvious with the dynamic camera and background that relies primarily on resized text for decoration.

Will be like that as decorative text is pretty special. Maybe we will tweak it in later versions.
