[Piglit] [PATCH 3/3] glx/glx-multithread-texture: Use larger color differences

[Thomas Hellstrom]

Color spacing of 1 between consecutive textures may yield false positives
when probing, and defer error reporting to the transition from color 255 to
color 0. That may be confusing. So increase the color spacing to detect
errors earlier.
