Subject: Use the right pitch when rendering to a texture
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3f30b0709b5a71915df336194f9f805e4c306cef;p=mesa.git

Use the right pitch when rendering to a texture

We need to get the pitch from the texture level we are rendering to,
rather than just using the base texel width.
