Window client size is incorrect due not using AdjustWindowRect about d3d9 HOT 1 OPEN

You are right, the borders are not taken into account by the 640x480 given to CreateWindow. In this case though, that was actually my intent. I have tried this library on virtual Windows XP machines with 640x480 resolution. In this setup the window should not be larger than the screen, I actually really mean a 640x480 window, not client here. For this basic example the thing to show is how to get a triangle up on the screen. It is not intended to show inane Windows API quirks. They annoy me, I know about them, but this is not the place for them I think.

But thanks for the suggestion. I guess a way to solve this is to have multiple tutorials/examples, going from small-scale to large. We could have a nice tutorial with all these real-world problems that someone will face trying to create a real desktop 3D application, concentrating on one topic at a time. Unfortunately this is very time consuming and the thing I do not have right now is time...
