Oops! Didn't see that you had done that.

I can confirm that, with these patches applied, Allegro compiles fine
(DJGPP), and that the example programs all work as expected; however, I
don't think any of them would be affected by your patch. I believe we
need some more example programs to show the new capabilities. Perhaps
expanding ex3d would be a good idea? We could incorporate exzbuf into
it. Or perhaps we could add a test3d program; this would be similar to
test, but would be for the 3D functions.

On a side note, I tried Tom's library `More3D', but I found that it
didn't work correctly (either with or without this patch). In mode 1
(RENDER_SORT), everything is displayed fine (assuming that the cube is
meant to be a wireframe thing) and the output looks very nice. In mode 2
(RENDER_P3D), the cone's curved surface is displayed correctly, as far
as I can tell, but the bottom is horribly distorted. Also, the cube
appears and disappears depending on what I'm doing with the mouse, and
is not rendered properly at all even when it is visible (it is texture
mapped, though; not wireframe).

Tom -- have you seen this problem yourself? Is your patch meant to fix
that? I was using latest CVS version, updated 1/2 hour ago, with Charles
Bilyue's i386 blit optimization patch applied, both with and without
your two patches.

Bye for now,
