+d3d_caps logs of i810 and i915 for comparison, zipped

The splines bug is still present in wine-1.1.18/19. Likewise, during game play,
the set of icons displayed in a circle around the selected object are still
empty (the white symbols are missing, while the surrounding blue or yellow
disks are rendered correctly).

Now I could test the app on two similar machines. One i810, one i915 Intel
driver. The bug is currently not present on the i915 machine with Ubuntu
Intrepid, but still present on the i810 machine.

Attached are:
- a d3d_caps log of Crazy Machines Inventors Workshop (Erfinderwerkstatt) from
wine-1.1.18 running with i810 HW on an Ubuntu Intrepid a little bit late on
updates.
- a d3d_caps log of Crazy Machines IW from wine-1.1.19 running on i915 HW on a
version of Ubuntu Intrepid with recent security updates.

The main differences seem to be:
- max 4 instead of 8 texture/stages & fragment or combined samplers
- no ARB_fragment_program
- 1.3 Mesa 7.2 vs. 1.4
- Pixel shader disabled vs. Hardware pixel shader version 1.4 enabled

But that cannot be all, since the i810 machine showed no splines in Suse 9.2
years ago, running some very old release of wine, whereas they were present in
Ubuntu Dapper at the same time.
Thus it is not the case that the i810 HW is too poor for this game.


BTW, another (or related?) issue is that the i915 produces
[driAllocateTexture:636] unable to allocate texture [2 times]
when running Crazy Machines Operation Brainstorm (CrazyMachinesOB) with
wine-1.1.19.
