It doesn't matter wich commit the apitraces are played back on, the first one
is always good and the second one always bad. However, playing back the bad
apitrace on good Mesa gives lots of warnings like this one:
3444 @0 glGetAttribLocationARB(programObj = 6, name = "xlv_TEXCOORD0") = 10
3444: warning: vertex attrib location mismatch 10 -> -1</pre>
