[PATCH] tests: Adjust some primitive tests to cope with reported failure.

[Peter Wang <tjaden@xxxxxxxxxx>]

Tobias Hansen reported that the hl thick-50 tests where failing on an
i386 chroot on a amd64 host.  The output differs in a single pixel in an
al_draw_spline call.  I am unable to reproduce the output, so this
change adjusts the failing tests to draw the spline without a rotation
transform, hopefully to minimise floating point differences.
