-------------------------------------------------------------------
-- To use this module add:
-- local scratchdrop = require("scratchdrop")
-- to the top of your rc.lua, and call it from a keybinding:
-- scratchdrop(prog, vert, horiz, width, height, sticky, screen)
--
-- Parameters:
-- prog - Program to run; "urxvt", "gmrun", "thunderbird"
-- vert - Vertical; "bottom", "center" or "top" (default)
-- horiz - Horizontal; "left", "right" or "center" (default)
-- width - Width in absolute pixels, or width percentage
-- when <= 1 (1 (100% of the screen) by default)
-- height - Height in absolute pixels, or height percentage
-- when <= 1 (0.25 (25% of the screen) by default)
-- sticky - Visible on all tags, false by default
-- screen - Screen (optional), mouse.screen by default
