-- To use this module add:
-- local scratch = require("scratch")
-- to the top of your rc.lua, and call:
-- scratch.pad.set(c, width, height, sticky, screen)
-- from a clientkeys binding, and:
-- scratch.pad.toggle(screen)
-- from a globalkeys binding.
--
-- Parameters:
-- c - Client to scratch or un-scratch
-- width - Width in absolute pixels, or width percentage
-- when <= 1 (0.50 (50% of the screen) by default)
-- height - Height in absolute pixels, or height percentage
-- when <= 1 (0.50 (50% of the screen) by default)
-- sticky - Visible on all tags, false by default
-- screen - Screen (optional), mouse.screen by default
