/*:
* @plugindesc Removes limits on scrolling text speed by overriding editor value
* @author NoInkling
*
* @help
*
* Plugin Command:
*   TextScrollSpeed x  # Where x is any number above 0
*
* Notes:
*  * Decimal values can be used, e.g: TextScrollSpeed 0.5
*    (numbers below 1 can be very slow!)
*  * It makes no sense for the scroll speed to be 0 or lower, in these cases
*    the editor value will be used instead.
*  * Very high values may cause unexpected behavior, use caution.
*
* The plugin command will only have effect on the next executed
* "Show Scrolling Text" command.
* If your event has more than one set of scrolling text where you wish to avoid
* the limits, you will need to use the plugin command before each one.
*
* A specific plugin command is only valid for the current event page; if a
* "Show Scrolling Text" command is not subsequently encountered on the page,
* that particular plugin command won't do anything.
