Issue 110 sharper bubble corners

Adjustments made to insets to sharpen up the appearance of the bubble on the top/right edges.

I'm still trying to figure git/github out. I created 3 different branches to encompass the 3 different fixes I'm trying to do pull requests for. The first one worked fine. Now this one and my third show the changes that were also included in my first branch. Is there some way for me to 'remove' those changed files from this branch, or from this pull request?
