This is a little tooltip mod I made that just does what I want... reposition, scale, and adds a border texture to match my layout. If you want a tooltip mod that has all the bells and whistles, this is not for you. For the minimalist that just wants to change some basic tooltip attributes through lua, this may work well for you too.
As I'm still learning lua, I took bits and pieces of code from other mods to get what I wanted. Also the border texture is from a compilation I found as I was looking around on some of the various mod sites. Thanks to the other mod authors whose work I perused to make this little mod!
NOTE: Please read the readme.txt file before installation (which is included in the etooltip folder).
