[Mesa-stable] [PATCH 06/35] meta: Fallback to software for GetTexImage of compressed GL_TEXTURE_CUBE_MAP_ARRAY

[Ian Romanick]

From: Ian Romanick <ian.d.romanick at intel.com>

The hardware decompression path isn't even close to being able to handle
this.  This converts the crash (assertion failure) in
"EXT_texture_compression_s3tc/getteximage-targets S3TC CUBE_ARRAY" to a
plain old failure.
