Hi all, as promised, here are the patch files for MS Windows to use Device Independent Bimaps to speed up.

Thanks a lot for your work Thomas.

• About the "get rid of GRXMain" part:

I will integrate it in the next pre-release. I have changed the vdriver a bit, I think is much cleaner. I attach it for review.

Good to hear. I'll check it.

• About the DIB aproach:

Is very interesting and really fast!. But now than you have a pointer to a "24 bpp linear frame buffer" (the bitmap), why not use the standard GRX framebuffer with them?

The idea is to clone the fdrivers/lfb24.c in fdrivers/lfb24w32.c (by example) using a new driver name (like GR_frame24W32_LFB by example). I suspect the only things to add are the apropiate InvalidateRects.

Hmm, I have been stealing in ram24.c, apparently I have been searching in the wrong places. Looks to me like a major peace of surgery, but thanks for the pointer. At least I will have to change the DIB to being a top-down bitmap instead of being bottom-up. I do not have the slightest idea why MS made that the default.

Ciao Tom
