As a special case, a value of 255 (0xFF) disables the "realistic train braking is aspect limited" setting entirely for signals using this style.<br />
This should only be used for signal types which are intended to emulate in-cab signalling, instead of the "driver" visually reading a signal.

This property only makes a difference when the "realistic train braking is aspect limited" game setting is enabled, or when using a different signal
type which uses <span class="code">tyle_combined_normal_shunt</span>.<br />
This is similar to <span class="code">style_lookahead_extra_aspects</span> with a value of 0, except the lookahead always ends at the
next signal, even if that signal type sets <span class="code">style_no_aspect_increase</span>.<br />
