+/*
+Tooltips v1.1 - 22/10/15
+Developed by Wire (#goonstation on irc.synirc.net)
+- Added support for screen_loc pixel offsets. Should work. Maybe.
+- Added init function to more efficiently send base vars
+
+Configuration:
+- Set control to the correct skin element (remember to actually place the skin element)
+- Set file to the correct path for the .html file (remember to actually place the html file)
+- Attach the datum to the user client on login, e.g.
+/client/New()
+	src.tooltips = new /datum/tooltip(src)
+
+Usage:
+- Define mouse event procs on your (probably HUD) object and simply call the show and hide procs respectively:
+/obj/screen/hud
+	MouseEntered(location, control, params)
+		usr.client.tooltip.show(params, title = src.name, content = src.desc)
+
+	MouseExited()
+		usr.client.tooltip.hide()
+
+Customization:
+- Theming can be done by passing the theme var to show() and using css in the html file to change the look
+- For your convenience some pre-made themes are included
+
+Notes:
+- You may have noticed 90% of the work is done via javascript on the client. Gotta save those cycles man.
+- This is entirely untested in any other codebase besides goonstation so I have no idea if it will port nicely. Good luck!
+	- After testing and discussion (Wire, Remie, MrPerson, AnturK) ToolTips are ok and work for /tg/station13
