OpenGL is here

Finally got round to porting across to OpenGL. It's so much faster. With the same number of objects (78) and no optimisation (i.e all objects redrawn every frame) I'm getting 1300 frames per second in windowed mode, compared to 50fps when using Windows GDI. That's a nice healthy number since my target is 60fps. Still got some bits to do and my textout function seems to take a huge chunk out of the framerate so it runs a lot slower when in debug mode with all sorts of data on screen. Although 1800 won't be the final framerate since I'm expecting to have hundreds of objects on screen at the same time so this will obviously slow things down but it does mean I've got a lot of room to play. Once I've got it running properly with that many objects I'll start adding the selective redraw stuff and maybe double linked lists to speed up the sorting algorithm. My friendly host JDarling from EonClash has given me some pointers on linked lists so I'll be reading up on that soon enough. I'll post some screens and a new download very soon.
