Started adding support for scrolling reel displays, currently text
only, but should be pretty easy to get graphics in there and add different direction scrolling - updating sc4 code to use these new types. [David Haywood] Stepper display output fix [James Wallace]

NOTE: Fading lamp system currently only recognises three lamp states:
|
||||
|
||||
0=off, 1, 2= fully on
|
||||
|
||||
Based on evidence, newer techs may need more states, but we can give them their own
|
||||
handlers at some stage in the distant future.
|
||||
|
||||
Instructions:
|
||||
In order to set up displays (dot matrices, etc) we normally set up the unique
|
||||
displays first, and then add the remainder in order.
|
||||
|
||||
The priorities (in descending order) are:
|
||||
|
||||
Full video screens
|
||||
Dot matrix displays
|
||||
Other, as yet unknown devices

This is a primitive handler for generating reels with multiple symbols visible
