;---------Done---------
;input protection //
;thin display lines  //
;crosshair reference? //
;make display follow cursor //
;tidbits scrolly change value thingy  http://www.ahkscript.org/boards/viewtopic.php?f=6&t=219 //
;lock capture at edges of screen /// (mega fix'd :D) (thankyou spoon)
;Another hotkey to show preview (with title bar for dragging) //
;Add cursor support (spoon did this already and didn't tell me... FUCK!) ///

;---------Buggy but working---------
;multi-monitor kinda working :) (helps if your monitors are the same resolution)

;---------Todo---------
;Relative/absolute coord toggle for output ?? (forgot what this means // see below line)
;configurable coords for persistent box
;Configurable hotkeys
;stop the settings lines resetting to middle when you adjust values

;move persistent box on mouse hover
;brightness contrast
;persistent box timeout
;option to remove title-bar from persistent box, toolwindow?

Name: Wheel &  Drag
Version 1.0 (Thu October 10, 2013)
Created: Thu October 10, 2013
Author: tidbit
Credit: AfterLemon - detecting a bug some people may or may not get.

Description:
   * Allows you to change numeric values in edit controls by
   dragging the mouse and/or scrolling the mouse wheel.
   * Two modes for Dragging exist, up/down and left/right.
   * Please see the comments of the functions aswell as the
   demo code for more information.
