[Mesa-dev] [PATCH 1/2] meta: use _mesa_set_enable(), fix decompress_texture_image()

[Brian Paul]

From: Brian Paul <brianp at vmware.com>

Use _mesa_set_enable() to avoid a redudant context lookup.
Need to disable the texture target in decompress_texture_image() so the
unit isn't still enabled after glGetTexImage() returns.  Arguably, the
meta restore code should do this, but it doesn't.
