Subject: [PATCH] Improve image quality of PNGs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The PNGs we were generating looked a bit fuzzy, and the text rendering
was a bit off.

This is because we weren’t rendering them at a high enough resolution.
I’m guessing the default was 72dpi. This commit increases the resolution
to 96dpi, which (locally) seems to be enough to give a good-looking
preview.
