Subject: st/mesa: add some debugging code in st_ChooseTextureFormat()
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=daf23bd4cb944e1d78664b6780a78d021c0cec79;p=mesa.git

st/mesa: add some debugging code in st_ChooseTextureFormat()

I've temporarily added code like this many times.  Wrap it in a
conditional that can be enabled when needed.
