One case can be solved by the tolerance (though I did not want to
introduce it as the other cases match exactly), but the two others are
about sin and cos from FLOAT_MAX value, and the difference is big. It is
BTW a sort of msvcrt issue in my understanding. My (Wine) results match
exactly native d3dx if Wine's msvcrt is used by native d3dx, and do not
match when d3dx is using native msvcrt (and there is also the difference
for that between Windows version). Native msvcrt is apparently using one
of many possible tricky sin/cos/sqrt computation in Win32.
I was curious if there is a legitimate Windows version dependent
"wine_if", or some check for Wine version, or better exclude such test
at all from comparison?
