[PATCH 1/3] ddraw/tests: Reduce precision in test_filling_convention.

[Stefan Dösinger]

Signed-off-by: Stefan Dösinger <stefan at codeweavers.com>

d3d9 and earlier cards fail this test (tested on r500 and by Matteo on a
gf4go, aka gf2). Since applications using ddraw.dll are unlikely to
depend on the higher precision of d3d10+ cards, unconditionally increase
the added offsets in the test.

As far as my hardware is concerned we can now remove the todo_wine in
this test because the offset we add for the "nudge" primitives is larger
than the offset wined3d adds for correcting the filling convention. I'll
wait for Matteo's word on the geforce 4 though.
