[PATCH 1/6] d3dx9: add test for preshader in effect.

[Paul Gofman]

PS Besides there is an issue with Inf and Nan FP comparison. There are
currently no NANs in this table, but there are some INFs. I thought it
is safer to compare these as integers, otherwise explicit testing for
Nan (and possibly for Inf, though not strictly necessary) will be required.
