Owner draw

While doing sm_Ellipses.jpg some ownerdraw stuff in regular Windows stuff (stuff is my favourite word, as you can see), I noticed something weird: I was forced to ‘refresh’ regions by code, instead of relying on the tools of the specific programming language. For a single moment I was thinking I was seeing ghosts, but apparently, I wasn’t hence the use of a refresh in a specific piece of code that allowed me to merge a couple of cells in grid.

Now for the gifted among us, how do I make that ellipse look 3D (and don’t tell me to shift the ellipse a couple of pixels up or down, drawn in a different colour).
