Comment (by mlennert):

 Thanks for all these fixes !

 r.texture now runs much faster than before and results seem more
 meaningful. I'll attach an image with results of running

 {{{
 r.texture lsat7_2002_80 -a
 }}}

 using 7.0.5 (left) and current trunk (right) for each of the texture
 indicators. On 7.0.5 this takes over 2 minutes, where in trunk it takes
 less than 30 seconds.

 Several results now seem more relevant (SV, SA, DV, Contrast). Others do
 not change. I don't know whether this is because they were already ok or
 not. Variance seems to be less clear after the change. And MOC-2 doesn't
 give any result (0 everywhere) in both versions.

 I think r.texture is already much better than before, but still needs some
 serious revision to make sure that all the indicators are actually
 calculated correctly.

 I don't know if we just leave this bug open, or whether we should open a
 separate bug.
