    llvmpipe: Temporary workaround to prevent segfault on array textures.

:040000 040000 98a1ae9d47b556629ed257353cd5c93f6d660517 3a99f61bbde526d04c60d10629f5801e05e8d235 M	src

Comment 1 Roland Scheidegger 2013-05-18 03:03:56 UTC 
The workaround was bogus since it didn't only prevent the wrong first_layer rebase (which wasn't an issue for opengl) but had the effect of not assigning depth correctly (so was always one, effectively reducing all array textures to non-array ones).
This is however already fixed by 87978518e996d02e055174d7152fff150fe3cd13.
