D2DControl usage

Hi,

I am just starting to explore this library and looking for an example of proper D2DControl usage. My main question is what the best practice is for triggering OnRender? The only way I have been able to make it work is through a timer driven call that invokes Invalidate() every N milliseconds on my D2DControl derived control. This, however, results in 0 FPS with ShowFPS property enabled which makes me think I am not doing it right.

Thanks for any pointers or tips.

Start by reviewing D2DControl's OnRender, Invalidate(), and ShowFPS behavior, then reproduce the timer-driven example described in the issue. Done means documenting a supported way to trigger rendering and clarifying why ShowFPS reports 0 FPS; no source file or test is named.
