How to set default style for insertlayer in TinyMCE

[minneapolis_dan]

I'm using the newest version of CMSMS, and had this question. Using TinyMCE 'insertlayer' , with the layer plugin, it automatically styles it with the following:
position: absolute; left: 0px; top: 20px; width: 100px; height: 100px;

This isn't a huge issue, but a bit annoying, especially because I can't find a file where I change this default behavior. Anyone know where I can edit this?  I'm searching Moxie's site too, not finding an answer.
