OC-KittenOS/code/libs/neoux.lua
20kdc de822181bc Hopefully work out a corrected solution to the legal fun, and fix control, textedit, taskmgr, neoux, everest and glacier
taskmgr and textedit had issues with the DEL key
neoux needed clipboard support that worked
control... I forget
glacier missed a pcall
everest's launcher change support wasn't working
compliance.lua was accused of being itself

-- neoux: Implements utilities on top of Everest & event:
-- Everest crash protection
-- Control reference
-- x/y/w/h: ints, position/size, 1,1 TL
-- selectable: boolean
-- key(window, update, char, code, down, keyFlags) (If this returns something truthy, defaults are inhibited)
-- touch(window, update, x, y, xI, yI, button)
-- drag(window, update, x, y, xI, yI, button)
-- drop(window, update, x, y, xI, yI, button)
-- scroll(window, update, x, y, xI, yI, amount)
-- clipboard(window, update, contents)
-- Global forces reference. Otherwise, nasty duplication happens.
