-- To use this module add:
-- require("teardrop")
-- to the top of your rc.lua, and call it from a keybinding:
-- teardrop(prog, pos, edge, height, width, sticky, screen)
--
-- Parameters:
-- prog - Program to run; "urxvt", "gmrun", "thunderbird"
-- pos - Position; "bottom", "center" or "top" (default)
-- edge - Edge; "left", "right" or "middle" (default)
-- width - Width in absolute pixels, or width percentage
-- when < 1 (0.9999 (99.9% of the screen) default)
-- height - Height in absolute pixels, or height percentage
-- when < 1 (0.25 (25% of the screen) default)
-- sticky - Visible on all tags, false by default
-- screen - Screen (optional), mouse.screen by default
