If anyone is interested, I wrote a quick demonstration of one virtual grid control and the advanced surface rendering interface which are part of Cross Codebot, a cross platform LGPL Lazarus toolkit.

Look for release soon. I still need write a few more demo programs and finish recording a few more tutorial videos.
